here is significant dispute that Elizabeth is the mother of Mary Warren. She may be the second wife of Richard. She came to the new world with Richards four daughters and bore him two sons in Plymouth.
She appears to be decended from King Edward I of England (Rixford), but there is some question also that she was the wife of Richard Warren of the Mayflower (Genealogies of Mayflower Families, vol III, GPC 1985; pg 619).
Susan Roser, in "Mayflower Births and Deeds" Vol 2 (1992) footnotes on page 455 cites Plymouth Church Record 8:35 as saying "Mistris Elizabeth Warren, an aged widdow, aged above 90 years, deceased on the second of October, 1673, whoe, having lived a godly life, came to her grave as a shoke of corn fully ripe." If accurate, this would indicate that Elizabeth Warren was born in 1583 or before. As such, she could have easily been the mother of Mary Warren (daughter of Richard Warren of the Mayflower), a Churchill ancestor.
Roser also says that "Wife Elizabeths maiden name has not been found." LDS cites it as Jouatt and Rixford cites it as Jouett. Rixford suggests that Jouett is Jewett.
Rixford cites "Jewetts in America" by Fredrick Clark Jewett and Harlean Society Records Vol xviii, "Jewetts of England and America".
The Rixford genealogy of Elizabeth Jouatt Warren is included for recording purposes. Much research seem necessary to verify this rather slim thread of evidence. [STRUBE-1.GED]
