Jennifer...my email is firstname.lastname@example.org
. Feel free to contact me there.
I don't know how much I can help with this family...William DeWitt Wohlfarth (Richard and Gilbert's brother) was married to Ruth Packer, and I am related through the Packers. Dewitt was a close friend of my grandfather Karl Hoffsommer, as well, and my grandparents often visited Ruth and Dewitt in Florida after their retirement, and decades earlier when they lived in Pittsburgh. I do have some letters to my grandmother from Ruth.
Interestingly enough I have many other Wohlfarths in my tree, though, and it might be interesting to compare notes. I have so far not been able to find a link between the Wohlfarth families I have in my tree, but that doesn't mean it isn't there!
