598 County Route 20, Oswego, New York | Unmarked Location
Whenever she was resident in Oswego, Mary Edwards Walker lived in the house where she was born. When she was too ill to live independently, nearby neighbors—the Dwyers—took her in. She died in the Dwyer house on February 21, 1919, aged eighty-six.
The ultimate fate of the Dwyer residence is not known. Whatever may have befallen it, sometime after the midpoint of the twentieth century it was replaced by the Colonial-style suburban that occupies the hilly site today.
