Sheldon asserts that the first Matthew Clesson had two sons Joseph, one born in 1675 and died before 1683, the second born about 1683. Trumbull only has one Joseph. It's unlikely that a boy of 15 would have been involved in the Pomroy pursuit as a dragoon in 1698 [see Deerfield History 1:261-62]. Fort William Henry was constructed in 1755 and destroyed by the French in 1757 making it unlikely that Joseph Clesson was buried there in either 1753 or 1758.
