Dorothy Thomas not Tho East 1st wife

Thomas East Sr states in 1680 that he is 40 years old.This Thomas East married SECOND Dorothy Thomas in 1686 at St John's Church in Henrico Co, Va.In 1695 Thomas East Jr states he is 28 years old.In several deeds Thomas East Sr names his son Thomas, daughter Mavel (who married John Robinson before June 1690) and in March 1697 Dorothy East releases her dower right to her SON IN LAW, Edward East.So with Thomas East Jr's age, Mavel's marriage and this deed concerning Edward, Dorothy is not the mother of any of Thomas East Sr's children.Does anyone know who was?Thomas Sr seems to have died in 1726 (age 86!) leaving things to a daughter Mary.Is Mary Mavel or did Dorothy and Thomas have a daughter Mary?
