[Church register of Capel St. Mary, baptisms] Abigaile daughter of Isacke Mixer and Francis his wife 1 Nov.
↑ 2.02.1Source:The New England Historical and Genealogical Register, p. 66:179, "Genealogical Research in England", notes there is a baptism record for Abigail, but Amy is mentioned in her father's will, and speculates they are both the same person? It is conceivable that another daughter named Amy could have been born between 1613 when Abigail was born and 1620 when the mother Frances died, and that Abigail could have died without heirs before 1642, leaving only Amy to be named in the will, but as no such evidence has been found, the article's speculation may be a good guess.
