Joseph Davis, Mary Bigelow Davis, and Moses Davis

Does anyone have any information on Joseph Davis and Mary Bigalow (Bigelow). They were married in Greene County, Ohio on February 19, 1829. I'm trying to determine if they are the parents to my gggrandfather Moses Davis. He was born on 24 June 1831 in Greene County, Ohio. On his pension records it lists his Father as being Joseph, no additional information was given. I believe they had at least 2 other sons, Phillip and Josiah. Also from the 1880 census, both Moses and Phillip list their parents as being born in Delaware. Any help would be appreciated.
