If Eleanor Robson Belmont is in this photo, I think Bain may have misplaced his "X" - the woman at far left looks more like the photo included in her Wikipedia entry: en.wikipedia.org/wiki/Eleanor_Robson_Belmont Assuming this was taken ca. 1910, she would have been in her early 30s.

rockcreek: Looks like you are correct. We will make a note of it in the source data and reload the description.

It may be worth double-checking if the woman at center is Mrs. August Belmont Sr. - perhaps she was still alive at the time? I'm not able to find an image of her online at the moment.

Or might be the wife of the third August Belmont (1882-1919), married in 1906:

is Mrs August Belmont, III
See Bain photo (with comments) that is probably of her, captioned Mrs. A Belmont, Jr.:

This isn't the wedding, but she is: MRS. GILBERT, BRIDE OF CAPT. DUGMORE; Widow of H. Bramhall Gilbert Married to British Army Officer at Her Home. January 20, 1914, Tuesday. The wedding of Capt. Cyril Patrick William Francis Radclyffe Dugmore, late of the British Army Corps and now on the reserve of officers, and Mrs. Lilla B. Gilbert, widow of H. Bramhall Gilbert and a daughter of the late William V. Brokaw, was celebrated quietly yesterday at 12 o'clock in the apartment of the bride at 903 Park Avenue.

The whipped cream of New York society turned out in October, 1912, for the eleventh annual horse show at the Piping Rock Country Club, in Locust Valley, on the north shore of Long Island. A new clubhouse and stepped observation boxes had just been opened for their pleasure: Story in The New York Times, October 4, 1912: "SOCIETY AMATEURS IN THE SADDLE "Piping Rock Horse Show Attracts Hunting Set to Locust Valley Grounds" query.nytimes.com/mem/archive-free/pdf?res=9D06E1D6113BE6...

Could these be the grandchildren of Mrs. Edith Cooper Bryce, wife of Lloyd S. Bryce, former United States Minister to the Netherlands? Upon her death on April 29, 1916, she left a life interest in more than a million dollars to her husband. When he died on April 2, 1917, it reverted to the residuary estate to be distributed among her children and grandchildren. A New York Times article of April 3, 1918, names daughter Edith C. Cram and grandchildren Henry G. Cram, Edith Bryce Cram, and John Cram, among other beneficiaries. query.nytimes.com/mem/archive-free/pdf?res=9A06EFD91E3FE4... The 1920 U.S. census for New York shows the Cram family living on Fifth Avenue in Manhattan: John S. Cram, a lawyer aged 62, his wife Edith C., age 38, their children Harry S., age 12, Edith B., age 11, and John S., age 9, along with a butler, a nurse, a cook, a governess, a housekeeper, a waitress, and a maid. All of the family members were born in New York with the exception of Edith C., who was born in Washington. Given their ages in 1920, it is likely that the photograph above was taken several years later than 1910, as Harry would have been two years old and Edith only one year old in 1910. My guess would be perhaps 1914, at ages six and five.

My goodness, even today that's a lot of money to inherit.
