I am a Newbie to this geneology business, so you will have to bear with me.
I may have overstated the "excellent" photo description, as it is a 4" x 6" actual portrait photo from Barron Photography in Port Huron, Mich taken sometime around 1880, I would guess. It's faded, of course, so it probably won't scan very well, but I'll give it a try. The inscription on the back simply says "Felix Tousley, father of Edwin Tousley" written by by grandmother (Edwin Tousley's daughter).
Your notes from Gertrude Jessup seem to jive as my gr grandfather, Edwin Rutven Tousley was born Jan 31st, 1850 in Wolf Island, Canada
I have no information on Felix Tousley's parentage.
I am attempting to attach a .jpg picture file for you.
Let me know if you received it or not.
