The Winninghams (sometimes spelled Willingham) were among the early 17th Century immigration from England. The earliest known, John, was often called William, as a nickname of sorts. The practice of using such nicknames was quite common in the north and east of England, so may help narrow the task of identifying him in the home country. James does not appear in the will of his father John, but his age and context puts him there. It seems much more likely that the document was mutilated.
