'Valentine Winfree, who died July 22, 1796, was a resident of Chesterfield county, Virginia, where he was a planter and landholder. He married Martha Johnson, who bore him four sons: Valentine, Reuben, Major, James.'
Note: The source of information is not identified, so it is unclear how much was known and how much was conjecture. The information is presented as background for the article about their great grandson Major Christopher Valentine Winfree, and presumably came, at least to some extent, from "family records". Note that only 4 sons are mentioned, whereas Valentine named 7 sons in his will. (The order they are listed in the will doesn't suggest that he had 2 wives with Martha being the mother of only the younger sons, although that could have been the case.) Their son Valentine named a daughter Martha Johnson Winfree, assumed to be after her grandmother, so the maiden name of Valentine Sr.'s wife rings true.
