I am also interested in Isaac P. Hines, married to Margaret Mahan. I am descendent from them and have been acquiring documentation (census, death certificates) to that end. I have been unable to make leap from Isaac's father Daniel, back however as Isaac's death certificate lists:

Father: Daniel Hines
Mother: Rebecca Shivers

Rebecca Shivers is new name to me. You indicate his mother is Sarah Treakle.....I have seen postings of Sarah Treakle married to Daniel Hines and Isaac Hines married to Sarah Patterson. (Both are sons of Rudolph Hines/Sarah Huff). My thought was that Isaac P., Edward S., and possibly William were brothers, and Samuel Treacle was a cousin. I believe them all to be Civil War Veterans with either 43rd OH VOL IN or 126th OH VOL IN. Any help, and/or document sources is appreciated
