William Lewis was the father of Capt. Meriwether Lewis of the Lewis and Clark Expedition.
The dates on his gravestone, erected by the DAR many years after his burial, are questionable. He probably was born between 1734 and 1738. His wife Lucy (Meriwether) stated that he died in 14 Nov 1779 and she remarried in 1780. The existence of the 1780 inventory of his estate, the tends to confirm the 1779 date.
