Is it possible that there was a Frank Perrin born in 1846 in your line? My gr-gr-gr grandfather was Frank Perrin and was born 1846 in Ohio. As far as I am aware (from my searching on Ancestry.com), his father was a William Perrin and his mother was a Mary Ann Wheeler (first name matches, at least). I don't know much about Frank's father or mother, but I do know Frank was in the Civil War and was married to a Marietta Chidester. If this sounds familiar, please email me at email@example.com. Maybe we can work together.
