Does this photograph show Teddy Roosevelt at Lincoln’s funeral procession?

See the house on the corner, at the left?  Look at the second story, at the window on the side of the house facing the camera.  Is that young Theodore Roosevelt watching Lincoln’s funeral procession?

Stratis, who posted this photo at Flickr, added the note at that window:

6 year old, Theodore Roosevelt watches Abraham Lincoln’s funeral procession from an upstairs window of his grandfather, Cornelius Roosevelt’s mansion on Union Square with his younger brother Elliott and a friend.  Teddy lived at 28 East 20th Street.

Is that accurate?  Is that his grandfather’s house?  I assume that it is not 28 East 20th Street, which is where he was born and the house of his father.

A timeline of TR’s life said he watched the passing funeral entourage:

• 1865  –  Watches Abraham Lincoln’s funeral procession from an upstairs window of his grandfather’s house on Union Square, New York City. With him are his younger brother Elliott and a friend named Edith Kermit Carow.

Interesting intersection of history.  This would probably be the only meeting of Theodore Roosevelt and Abraham Lincoln, though Teddy almost certainly knew Lincoln’s sole surviving son, Robert, pretty well.  Both were in Buffalo when William McKinley was assassinated; Robert Lincoln, having lived through his father’s assassination, and then been present at the assassinations of James Garfield and McKinley, declined an invitation to Roosevelt’s inauguration in 1905, not wishing to extend one of the oddest bad luck streaks ever imaginable.

Can you add details about the photo?

• Lincoln Highway News said the photo is now held by the New York Historical Society; also, the house of Theodore Roosevelt’s grandfather is gone
• Harper’s Weekly of May 13, 1865, featured a lengthy story on the aftermath of the assassination, the new President Andrew Johnson, events at the end of the civil war and an engraving of the funeral procession in New York City; see and read it at Son of the South.
• A stereographic version of the photo above can be seen at About.com
• Mrs. Lincoln could not say “no” most requests made of her in the days and weeks after the assassination.  Many American cities asked to hold services while the body of Lincoln was on its way from Washington, D.C., to Springfield, Illinois.  Consequently, astoundingly, there were 13 funeral services held for the dead president, including Baltimore, Philadelphia, New York City, Albany and Buffalo, New York; Cleveland, Columbus, Indianapolis, Michigan City (Indiana) (unscheduled), and Chicago, before the final service and interment in Springfield.
