Hi Sam:
My Mom is one of the descendants of the Cecil County Gonces, and I have quite a bit of information on them. Unfortunately, there are quite a few Thomas Gonces in my list, and I can't determine which is likely your great-grandfather.
Can you provide anything more to go on? Do you have any dates or places of residence/birth, etc. for the Thomas you are looking for - or could you provide what you do know?
I believe that, except for the very few Gonces in Missouri and Nebraska, all of the rest of the Gonces throughout the U.S. descend from the same family originally in Middleton, Delaware prior to the revolutionary war.
Feel free to contact me directly at
foberle@rcn.com if you want to. Although I don't know if the others are registered on Ancestry, there are a number of scattered Gonce cousins that I can put you into contact with (and we've found out that we are all related so far).
Although I am living in Illinois, I was born in Baltimore MD, where my great-great-grandfather John Thomas Gonce (and later some of his siblings and nephews) moved from Cecil County right before the Civil War.
I look forward to hearing from you and exchanging information.
Have a great weekend.
Frank
