Your David Bingman was the son of John Frederich Bingman, who went by his initials "J. F.".He was born Jan. 1, 1822 in Union Co. (now Snyder Co.), PA.J.F.'s parents were Henry Bingaman (1794-1861) and Christina Moyer (1797-1866).
J.F. was married at least twice, the first time to Susanah (sp?) Partch, who was listed in various documents as bothHannah and Susan.She died in 1859, so she was not David's mother.The second marriage was to someone named Jane.She was in J.F.'s household in Beaver Twp., Snyder Co., PA in 1860 and was named as his wife in an 1864 deed.She likely was the mother of David, who was born in Pennsylvania about 1867-68 and living in Noble Co., IN in 1870.Perhaps her name was Mary Jane, which would account for the name Mary that you cited in your posting.
