Hi I am also researching these same lines. My line is Cornelius born 1842 Washington twp, Van Wert, OH married 3rd to Sarah Wilmoth; his father is Orren born 1809 DeRyter, NY married 1830 Licking Co to Eliza Jane Cavett;his father and mother is Cornelius Sr born 1775/1777 Schnectay, NY and Olive Messenger (her parents are Isaac and Anna Ward).
There is a book "History of Van Wert" that can give you lots of info on neighbors. Also check Mercer and Licking Counties for Orren and Ashbel they were obtaining property there also. Grandson of Isaac and Anna Joseph Tuttle wrote a autobiography. If I can be of any assistance write me. Joyce Patterson from Sacramento, CA
