Did your John L. Sullivan move to Otanabee? I have that info. Well I learned that Timothy Sullivan son of Darby Sullivan died cutting a tree from my cousin. She has been researching the family for quite a while. Yes the family moved around a lot. I descend from Denis Sullivan who married Mary Condon. Denis's son Timothy Sullivan went to Pennsylvania where he married a 15 year old girl named Annie Stull she was of Pennsylvania Dutch heritage. There is some info in a book called "Peter Robinsons' Settlers" by Carol Bennett that is focused on our Sullivan family.
p.s. Would be great to share info on our Sullivan lines.
