1860 and 1870 Census records list the family of William H and Susan A Sweat in Marlboro County, Bennettsville, SC. William appears to be born around 1812. Susan appears to be born between 1802-1805. William is my ggg-grandfather.
I have seen other Sweatt pedigrees that list Williaim H as William K.
If you have supporting info indicating William's middle initial is actually "K" rather than "H", please share!
