It is so wonderful to meet a long lost cousin!
First, thank you so much for telling me about George's middle name. I didn't realize it was spelled with 2 Ps instead.
It seems like you have searched for some time for the missing link - what other avenues have you tried? I actually came across a reference via the LDS family search site however it was for a John Coffeen who immigrated from Ireland, founding the town of Cavendish, VT. It looked promising but the dates didn't seem to jive. I am tempted to get the microfilm on loan at my nearest Family Center to see if there is more info. I wanted to see if you had already checked it out and ruled it out.
I have thought about doing the DNA test but wasn't sure just how much information it provides. Did you get a lot of information about the Coffin lineage?
My line is Ira / George / Mabel A. Coffin Fitzpatrick / Mabel Anna Fitzpatrick Needer / Constance Needer / and me Shirley Aubrey Ryan!
Looking forward to our continued discussions!
