How the streets came to be: Subdivisions

My study of the street name origins in Rye and Port Chester revealed that most streets came into existence as a result of subdivisions of lands.  That is true of Mamaroneck as well.  There were about 37 large subdivisions through which new streets were created. This process began in Mamaroneck in 1851, with Rye Neck Villages and Washingtonville. 

Maps of all subdivisions were filed in the office of the Westchester County Clerk in White Plains, and all have been scanned and are available for examination.  I have examined each Mamaroneck subdivision.  The county’s maps are numbered, either from “1” on, or, if smaller,  they were placed in a book, so that a citation would read, for example, “13-26”, meaning that the map is in volume 13, p. 26.

The clue to finding each subdivision and its map number is the consultation of the three  Mamaroneck maps by G. M. Hopkins Co., done in 1929. Although the three main areas used in organizing this study are roughly equal in size, the number of subdivisions differ: Rye Neck/Shore Acres—10; Orienta—8; and Downtown and down toward Larchmont—19.  This last section is the most complex relating to subdivisions and therefore street names. 

Having the information on a subdivision may help to determine where the street names—and subdivision name—came from. This includes prior owners, the new owners, or developers. 

Of course, there are some streets that came into existence separate from a subdivision.  These tend to be older and more major streets, the Boston Post Road being the prime example. 

Virtually all of the subdivisions logically follow topographical dividers.  These are the Mamaroneck and Sheldrake rivers; the railroad; the Boston Post Rd.; and I-95. These main dividers have been used to create sub-sections of this study

Origin of street names

The origin of the names of streets is the major focus of this study.  I have been able to determine some but far from all of the sources.   In earlier subdivisions, Mamaroneck family names appear.  Later, it is more of a commercial rush to come up with names. 

The largest category of street names are the surnames of persons.  However, there was seemingly a habit in Mamaroneck to use first names—of wives, children or the like.  Mamaroneck, more than Rye or Port Chester, went in for first names. This was especially true in Rye Neck. There are approximately 82 streets with surnames and 24 with apparent first names. 

The source of surnames is often famous residents, major landowners, or wealthy individuals, some of whom once lived in the area of the street. A handful of streets are named after U.S. presidents.  A few are named for politicians.  But many others have arcane names, no doubt related to the developer of a subdivision.

The next largest type of names can be placed in the category of geographical names, including names of places and physical descriptions: about 44 in Mamaroneck.  Then comes what I could call “nature” names: some 33, including about a dozen tree names. There also about a dozen “happy” or “real-estately” names, such as Mt. Pleasant, Grand, Colonial. 

That leaves about 14 which don’t fit into any of the above categories.  Five of these are numbers.  Unlike Rye and Port Chester, there is a paucity of Indian names, except for Mamaroneck Ave.

A study like this is never really done, so any information on names will be most welcome. You can send information to paul.rheingold@gmail.com.

Sources of information

Beyond the maps themselves, there are two major sources of information drawn on in this study. The most important one is a history of Mamaroneck by a famous citizen-historian, Edward Floyd de Lancey, which appears as a chapter in Scharf, History of Westchester County, (1886), vol. 1, pp. 846-888. This de Lancey as well as others is mentioned throughout this study. {Cited  de Lancey (Scharf)) A second historical source of information is Charles Beard’s famous book, on Rye “Chronicle of a Border Town: History of Rye“ (1871), especially as to Rye Neck, which was not a part of Mamaroneck until the incorporation of Mamaroneck Village in 1895, (Cited as Baird).  Also of tremendous help is Google, including the Ancestry site. 

This study is also greatly aided by Mamaroneck resident Michael Meaney, a retired Journal News/lohud.com editor.  This help far exceeds editing and includes original research on former residents for whom streets are named.  This has involved reading old newspapers online. 

Illustrations

To make this study more readable, we have placed relevant images, of the person involved, the mansion that once stood on the property, views of streets, photos of street signs, and most importantly the subdivision maps as filed in White Plains. Some of these images are old postcards and some are from the Westchester Historical Society.

Rye Neck/Shore Acres—Section 1

Rye Neck

Rye Neck is the land north and east of the Mamaroneck River, running up to Rye.  It was developed as part of the Town of Rye and only became part of Mamaroneck in 1895 with the incorporation of Mamaroneck Village. This includes the Shore Acres section.

PART ONE: NORTH OF BOSTON POST ROAD

Streets before Subdivisions

Subdividing of land began relatively early in the Rye Neck area, with the large Rye Neck Villages in 1851. This was farmland owned by two Rye Neck residents, George Barry and Noah B. Tompkins—discussed below. 

 However, before that there were streets in the area, meeting the needs of travel and commerce:

--Boston Post Rd-- 1600s (a/k/a Main St)—this linked plantation to plantation.  In Rye Neck the Post Rd ran over a narrow crossing of the Mamaroneck  River near where Tompkins Ave is today. 

--Tompkins Ave (was a stretch of Boston Post Rd in its old course). Noah B. Tompkins (1837-1891). Charles Washington Baird  in his book Chronicle of a Border Town—History of Rye (1871) (cited hereafter as Baird) describes Tompkins’ role in the Civil War,  as a member of The Union Defense Committee of the Town of Rye. The committee collected funds to relieve the families of volunteers who enlisted in the war effort, and later to pay bounties to substitutes for local men who were drafted. Tompkins also served on the Rye Neck Board of Education and on the Union Savings Bank board of trustees. He is buried in Greenwood Union Cemetery.

--Barry Ave N & S.  (was First St).  George Barry—died 1866. George Barry is reported among the delegates to an October 1858 local Democratic convention for the Second Assembly District in Westchester held at the Westchester County Courthouse in White Plains. The delegates, from various towns, nominated Edmund D. Sutherland as the Democratic candidate for Assembly. They also elected eight delegates - not Barry - to a Democratic Congressional Convention that was to be held in Nyack in Rockland County. In the Assembly election, Sutherland lost by 306 votes to candidate James S. See the Eastern State Journal reported. See ran under a fusion party of Whigs and the temperance movement.

---Rail Road St (now Halstead Ave)

--Union St–post Civil War patriotic name

Alda Road was created sometime between 1911 and 1929 - the height of her fame. Her home was in Great Neck, Long Island. She published a memoir, Men, Women and Tenors, in 1937, and it is still available in the Westchester Library System. It does not mention Mamaroneck.

Notes on other streets

Map: Union Avenue plan, 1870: Tap on the image to see a larger version

Note re South Barry Ave:  In the 1870s, a street to be called Union Avenue was planned to run from South Barry across a bridge over the mouth of the Mamaroneck River to Orienta, which indicates that this development was by legislature and taking of lands, 1870. Fortunately, the road did not happen. See  Union Avenue plan, 1870, above.

At the foot of S. Barry Ave. lies the mansion built for Charles Osborn, a New York City stock broker, designed by McKim, Mead & White.  It was known as Tahoma, illustrated above.  The buildings are now owned by the Mamaroneck Beach and Yacht Club

--Taylors Ln-- Alexander Taylor  (1821-1896) – banker, businessman, member of the New York Stock Exchange. Born in Scotland; the family moved to the United States the year following his birth.  His country home, Linwood, stood on this lane, where he lived year-round starting in 1882.

 His son Alexander Taylor, Jr. (1848-1899)  was also a member of the New York Stock Exchange.  He is mentioned in Baird (p.514) as living near the head of Horseneck Creek. DeLancey (in Scharf) says Taylor’s home, “Chrismere,” was on a knoll facing the Long Island Sound. Perhaps all the same place as his father. Alexander Jr. was active in Republican politics.   

Note:: In the 1867 Beers map what  appears to be Taylors Lane runs down to Mamaroneck harbor, over land then called Guion’s Neck.  On Guion Creek is the Van Amringe’s Emery Mill, and on the water is A. Whitlock Steamboat Landing.

--Colonial Ct—olde name

--Shadow Ln--trees

--Barrymore Ln—famous Barrymore family of actors—Ethel Barrymore (1879-1959), shown above, had house on Taylors Lane near here. Barrymore Ln was created by 1961.

Section 2: Orienta

This covers what was called Delanceys Neck and later Orienta.

A.    Before 1900

The 1868 Beers map called Orienta shows the following streets south of the Boston Post Road:

Mamaroneck Ave—now Orienta Ave.

Bleeker Ave—see below

Heathcoat (not actually developed)

Walton Ave—see below

Delancey Ave—now Rushmore Ave

These were bounded on the north by the Boston Post Rd, which then ran where Old Post Rd is today.

The earliest owner on record in this area was Thomas J. De Lancey.  Thomas married Ann Heathcote.  The family owned this area until 1848. 

Note: the family name is spelled many ways.  For the street name and general reference, I am using Delancey; but for individuals, I’m using the way they spelled it.  As noted in the introduction, much of the history of Mamaroneck is taken from the chapter by Edward de Lancey in Scharf’s history. 

Thomas Legrand Rushmore, Orienta developer, Mamaroneck’s first mayor

In addition to the land he purchased from the DeLanceys, Rushmore also bought another large plot of land in Orienta, owned by Isaac Hall (see below); this was nearer the harbor.  On it Rushmore built a summer hotel, according to deLancey (Scharf, p. 854).

Subdivisions:

Edge-Water subdivision map, 1854 (pdf version):

**Edge-Water   1854 [map 677]  See map illustration above. This map shows abutters: Greacen, Hall, and Palmer, and was filed by Anthony J. Bleeker (1799-1884) of New York City, a leading real estate agent. (Edgewater was the name of the Flagler estate—see below.)

--Bleeker Ave—named after the auctioneer (the eastern end of this street had been called Union Ave., with a proposed road across the harbor to what is South Barry, which was called Union—see Rye Neck section of this study). 

--Walton Ave— early family in Mamaroneck, perhaps specifically for William Walton.

Also, map shows Delancey Ave, which became Rushmore Ave;  and also Heathcote, which was not developed (though part became Bloomdale Ave—see below).

**Delancey, Thomas—1858 [map 2-13]

--Cooper Ave—James Fenimore Cooper, novelist. His mother was a Fenimore, and he married a Delancey.

**De Lancey Park 1893  [map 1059] on property of Thomas Rushmore

--Rushmore Ave (was The Esplanade)

**Rushmore Subdivision  1895 [map 11-10]

--Hall St—for Isaac Hall (1799-1877), major property owner in this area

Later: --Royal Place—off of Hall—probably just a real estate name

**Rushmore, Thomas   1897 [map 12-33] See illustrated map below.

Rushmore subdivision map, 1897 (pdf version):

--Claflin Ave—probably John Claflin (1850-1938) of Larchmont, wealthy New York City merchant

--Stiles Ave.—probably William H. Stiles (c. 1826-1904) of Mamaroneck. Stiles was a member of Halsted & Stiles, New York City cloth importing merchants, according to a Brooklyn Eagle obituary republished March 26, 1904, in the Eastern State Journal of White Plains, see below. Stiles lived at “Quaker Ridge, Mamaroneck,” from 1865-1897. He was a landowner in this area. He was an active official of the Methodist Episcopal Church in Mamaroneck and was among a group of prominent laymen who established a church newspaper called The Methodist in New York City that was published from 1866 to 1885. Others involved in that effort included fellow Mamaroneck residents Thomas L. Rushmore and George I. Seney.

--Beach Ave, renamed: Fairway Ave—leads over toward golf course

--Sylvan Ln—probably nature name

-Seney Ave— George I. Seney, a New York City banker and philanthropist, who had a home in Mamaroneck. Note: A daughter  of Thomas Rushmore was Lily Seney Rushmore.

**Orienta Shore Hills  1916 [map 168]  Rushmore Realty Co. (no streets added)

**Greacen Point  1927 [map 3230]-  John Greacen (1818-1886). His ancestors were from Scotland, he was engaged in rubber manufacturing, and he owned considerable land in Rye. His residence, discussed below, seems to have been on what we now call Flagler Dr. Greacen owned the point and had his house on it, which he named Orient, as he could see the sun rise.  Eventually he added an “a” to the name and in time Orienta became the name for the whole area. 

De Lancey (Scharf, p. 860), states that the toe or peninsula of land that is now Flagler Dr had its ownership as follows: Isaac Hall (mentioned above) sold this land to Greacen, who erected a mansion on it.  Greacen sold to Henry M. Flagler, the Standard Oil baron who developed Palm Beach, FL, the railroad to Key West, and much else in that state.  He called it Edgewater Point. The same peninsula was named Satanstoe in the novel by that name by James Fenimore Cooper, and that name is still used today

Section 3: Mamaroneck Avenue area, Washingtonville, Fenimore, Harbor Heights

1.     Mamaroneck Ave. area

We can begin analysis with the 1867 Beers map showing the section which is above the Boston Post Road and west of Mamaroneck River. It shows the following streets, the totality of the development in this area.

Winfield, which is now Mamaroneck Ave. There was a Winfield Hotel on the upper avenue, demolished by the Thruway, which opened in 1958. See a 1956 photo of the hotel from the Westchester Historical Society online collection

Mt. Pleasant  Ave—happy name

Cross—now Elm St—tree name

High—now Prospect Ave—the view

Orchard—now Palmer Ave  The progenitor of the large and wealthy Palmer family in this area was Samuel Palmer ( ).  See de Lancey (Scharf, p. 858), who describes his large original holdings, eventually passed on to three sons.

Locust –gone?

Meadow—gone?                                                                                                                           

East of what is now Mamaroneck Ave

Mill—gone--Name relates to manufacturing

Race—gone—name relates to manufacturing—watercourse. The millrace ran down to a factory shown in the 1857 map. Doubleday & Dixon Hat company. 

Franklin –gone?

Washington—now Spencer Pl

Railroad—now Halstead Ave—see part 1, Rye Neck.

Also added later: Phillips Park Rd—parking behind Mamaroneck Ave. Named for Arthur Phillips (1923-2006), mayor of Mamaroneck from 1965-77. The passage way was built around 1980.

 And north of the tracks is Washingtonville—see below.

Of major importance to understanding the development of the downtown area, and an explanation for the subdivisions listed below which have factory names, is information taken from Scharf, The History of Westchester County (1886), p. 861.  In 1811 the NY state legislature passed a special act incorporating The Westchester County Manufacturing Society, to purchase lands and goods to meet the objects of the law.  Under this power, the Society in Mamaroneck bought two farms on the west side of Mamaroneck River and down to the harbor, owned by Gilbert Budd, totaling 244 acres. 

The company constructed a dam on the Mamaroneck River, creating the Factory Pond, and built a factory. A succession of owners did not manage to make a go of it, however, according to Scharf.  This caused a lot of legal confusion as to ownership of the land and led to a period of instability, but eventually leading to what follows

Downtown subdivisions

**Land of James C. Spencer—1885  [map 6-55,also 7-31; 1276 (1904) now is estate of Belle W. Spencer]

Grand Park: A monumental vision’s fatal ending

Now a little more history is needed to explain some of the following subdivisions. Andrew Wilson (1818-70) was for a while a major land developer in our area of Westchester.  He developed two major projects in Rye. In Mamaroneck, he bought upward of 2,000 acres, running north and west from the Boston Post Road all the way up through what is Winged Foot Golf Course today.  On this he planned a gigantic development, called Grand Park.  This was even to include a world-class university.  He got in over his head, went bankrupt and committed suicide.  See New York Times obituary, Sept. 22, 1870.

More of the Wilson and Grand Park story is online in The Loop, Jan. 21, 2019. A map of the “Grand Central Subdivision of Grand Park” (undated—but map 65 of Westchester County) that shows the main portion of the whole project—which was never developed—is illustrated here.  Note the plan for a hotel, university, and for a seminary. Also note that on the right it bordered “Sylvan Park” and on the north “Heathcote Manor” (which is in Scarsdale).The map states that Grand Park itself  was on the property of T. N. Hawley, presumably a farm. 

With Wilson’s death went the gigantic project, but the following developments did occur:

**Grand Park –First Subdivision–1870 [map 459] 113 lots  Andrew Wilson  (also see map 65)

--Grand—became Fenimore Rd—as in James Fenimore Cooper (1789-1851) —his mother was a Fenimore (He married a Delancey).

--Rushmore (see section 2, Orienta) —became Maple St—tree name

--Livingston Ave—prominent NY family, some intermarriage with Richbell family (see below as to Richbell)

--Highland Dr—it is

--Prospect Ave—older street, see above

--Hoyt St—north side of railroad—Hoyt family early settlers in Mamaroneck 

**Grand Park Addition to First Subdivision –1870 [map 467] (ordered by a trustee, one assumes of the Wilson estate) (see also map 460)

--Stanley Ave—possibly another family related to Delanceys/Heathcotes

--Bishop Ave-- possibly named for Bishop Heathcote DeLancey of Mamaroneck

--Palmer Ave—for Palmer family, see above

And this also involved development along Mt. Pleasant Ave. and Prospect Ave. 

**Westchester Manufacturing Society 1878 [map 670, also 870]--132 lots

--Mt. Pleasant Ave—see name discussed above

--Factory St  –became Prospect  Ave—see above

(at the time this development ran across the Post Road where the water treatment plant is now)

**Factory Properties 1884 [map 6-46]—lots from Mamaroneck River to Mamaroneck Ave.
