Thank you for your reply. It's very much appreciated. While I initially had a reply from some of family members who originally posted in this forum, communication stalled and the family decided NOT to share any information which was extremely disheartening particularly since we share great great grandparents. Two sons moved from Illinois to North Dakota where one of the descendants is a State Representative (one who withdrew his initial offer to help) and some of the others are well known in that area within the oil business. Photos of family currently hang in the Steele County Museum.
I've recently had my dna tested through 23andme and found another Devlin connection which may also open doors.
Thanks again for you help and I'll happily look into your leads.
