The family thought that the Portrait was done by Peale (more about this later.)
When I saw this painting (online), there could no longer be any doubt.
Pictured is Edward Stow; 1768-1847.
From Lawrence Park (see entry Feb 20)
A son of Edward and Mary (Belcher) Stow of Boston, but was born in New York City. He married, in 1793, Anna Brewer Peck, and lived for some years in Philadelphia. It was there that he met Gilbert Stuart and his wife and a great friendship ensued. In 1804 he returned to Boston, and from 1813 until shortly before his death, he was clerk or secretary of the new England Mississippi Land Company.
This portrait according to Park was done in 1802-3; this is further confirming evidence that the Portrait of Samuel Meeker was done in the same time frame, and in Philadelphia. The painting style, arrangement, accents (upholstered chair, drapes, papers), color; all strikingly & substantially, the same.
