William, son of John, was mentioned in the manor rolls of Stokenham, 3 Jan 1580/1 and in 1610 was called "William Marche, sen." in the rolls. He was probably identical with William Marche "the elder" of Sherford, Co. Devon, yeoman whose will was dated 29 Apr 1612, named the seven children of his deceased son, Richard, and surviving children of his own.
