I still couldn't find anything under Francis Sinclair using the wife's name as my search value, but I found both Elizur Talcott and Amos Hubbard.

I am so excited that you are interested in DAR. You will need to send me your contact information and then I forward to my National Chairman. Do not post any personal information to the message board, but instead send it to my address at h0meb0und@aol.com. The o's are zeroes. I look forward to hearing from you and getting you on your way to membership in DAR!

Sincerely,
Joyce
DAR VIS Volunteer
