The program of the 1997 Philadelphia Antique Show in an advertisement on p. 87 illustrates a fine portrait of Thomas Ashley (1788-1870), the son of Israel Ashley of Westfield, Massachusetts. This portrait was painted c. 1800 by the artist William Jennys. Sorry, I know no more about him and no more information is given about him in the ad.
Thomas Ashley's descendants should know of this portrait. I'm scanning it and will be happy to send a digital copy by email freely to any family members who wish to have it. It is too good to be missed by the family of his descendants.

If it were a portrait of a 19th century family member in my Pease family line, I'd very much hope someone would do the same for me.
