This is more or less a guess - that Mathew was William's son. He obviously had a close relationship to the James that married Susanna Morgan and died circa 1810. In 1810, Mathew West was counted next to William in the census:
p. 768; Mathew West, 3m -10, 1m 10-16, 1m 26-45; 2f under 10, 1f 16-26, 1f 26-45
