Robert BARTLETT arrived on the ship Anne in July 1623, along with passengers Mary WARREN, her mother, Elizabeth (WALKER) WARREN and her sisters, Ann(a), Sarah, Elizabeth, and Abigail.
The name of Mary WARREN's mother has only recently been firmly proven when, in December, 2002, researcher Edward Davies discovered the 1613 will of Augustine WALKER in which he mentions his daughter, Elizabeth WARREN, wife of Richard Warren (c1580-1628) (who came earlier on the Mayflower), and her three children Mary, Ann and Sarah. The full story of this discovery, as well as additional information on the WARREN family, is available at Caleb Johnson's MayflowerHistory.com web site.
