William Harris - Not the son of Major William Harris- what do you all think

William Harris’ father’s will. A careful study of Henrico County records will show that this is untrue. Thomas, son of Major William Harris, died unmarried, in 1679. Thomas Harris who d. 1679 has also been shown as brother of Major William, also untrue. There is nothing to show that Major William Harris had a brother named Thomas. Two widely used published works have perpetuated these mistakes.

I'm beginning to wonder, it's best to actually see the Will's - even when difficult to read-
