Possible middle or alternate name of Jacob, but that may be an error in secondary sources. See marriage notes.

Marriage of William Leffel to Sally (Sarah) Ohmart listed on p. 181, Vol. 2, as well as p. 83, Vol. 3, of Early Marriage Bonds of Ohio. Original record in Clark County Probate Court marriages Book 2, page 369. (George Heeter lists a marriage of Sarah Ohmart to Jacob Leffel, and Leona Betteridge's charts say "Jacob or William Leffel", but the marriage record seems pretty unambiguous.)
