Elizabeth Weeks, 1731 m: to Thomas Carnes

Elizabeth Weeks, 1731, is listed as the daughter of William Weeks and Sarah Tukey, (Woodward). Elizabeth's records show her mother as Mary. Can anyone rectify this difference? Also, Elizabeth is not listed as a daughter of William and Sarah in "Genealogy of the Family of George Weeks of Dorchester, "Mass.
