Notes for MARGARET (UNKNOWN): There are many land grants and deeds in Richmond County, North Carolina to MacKeachey's; one or the grants in 1780 is to Margaret MacKeachey who would have had to be a widow to qualify. She seems to be the mother of John, James, and George, for James MacKeachey sold that land in 1823 after his move to Mississippi. The assumptions is, that William and Margaret were married before the birth of James in 1749 and had nearly grown children before their move to America from Ireland. The children that are listed are the only ones documented. The size of families during this time averaged 5 to 9 children. So it's assumed that there were more children in the MacKeachey family that are not documented or not yet found documented.
