Notes for Edward Sanderson: The source from the Family Search Ancestral File states that Edward lived from 1615-1645, and that he was born as well as died in Massachusetts. The WFT #77 states that he lived from Aug 17, 1602 to February 19, 1673, and that he was born in England.
His son Jonathan is listed in more than one place as having been born in 1646, which fits better with the WFT date. Also, his brother Robert is listed uniformly to have been born in England, so it seems that the WFT facts may be more accurate.
