Mary Sherburne Bowers
Painted by John Singleton Copley
from Bulletin of the Metropolitan Museum of Art, New York, Jan, 1916.
She was married to my 6 times great uncle Jarathmel Bowers (1720-1799). He was ancestor to my grandmother, Ada Swasey Rogers, or rather his sister Mary Bowers was (1719-1823) who married Joseph Swasey (1714-1801).
I'm not going into her parents' names, because it seems the more famous people were, the more different biographies there are. (see 2 below) Her father was probably considered rich and famous in his lifetime, Joseph Sherburne, Esq. I know he was married 3 times, but am not sure which wife was Mary's mother.
He had a portrait also painted of himself, by John Singleton Copley. I'll let you make your own opinion of it.
