Where did Eleanor & Franklin D. Roosevelt live in 1918?  A relative,
Ferdinand Vingiprova, was a chauffeur.  His WWI draft card shows he
was employed by a Mrs. F. Roosevelt at 830 Park Ave, New York
City.  Could this have been Eleanor?

Hello.

Eleanor & FDR's 1918 New York City address was 49 East 65th Street.

sources:

" In 1908, they moved into the 49 E 65th Street townhouse (adjoining
Sara's home at 47 East 65th Street) SDR had built for the couple as a
Christmas present. This remained the Roosevelt base in New York City
until SDR's death in 1941.  FDR then sold the house to Hunter
College."

I realize that this address probably isn't the one that you wanted to
hear, but, as indicated above, 49 east 65th Street was clearly the
Roosevelts' Manhattan address during the relevant period.  Thank you.

This was a very fast response and very well documented so that I am
sure the answer is the correct one.

Hi,

Your relative would have been employed by Mary Loney Roosevelt. She
was the widow of Frederick Roosevelt, a second cousin of President
Theodore Roosevelt, who died in 1916. Mary Loney Roosevelt is listed
in the 1920 and 1930 census records at 830 Park Avenue and died at
this address after a long illness according to her NY Times obit of
March 12, 1936.

Orazio:
Thank you for the tip.

Perhaps Eleanor should have had a professional driver.  My mother
lived near the Roosevelts' Hyde Park, NY (upstate from NYC) residence
from the 1930s through the 1960s. It was well known in the area that
Eleanor was a terrible driver and was involved in many fender benders.
 The advice was that if you saw her driving, you should get out of the
way.

Many thanks to quadro-ga and aj999-ga  for the added info.  Both will
make great additions to my family history!
