My son in law is the son of Ann Dambra Yetton, and her grandparents are the same as your boyfriends. I have tried to contact Nancy and the e-mail doesn't work. Did you ever get in touch with her and did you get any family information? I'd love to get as much as possible and if there are any family photos, I'd love to have access to those (scanned if possible).
Would love to hear from you,
