I have traced these folks quite easily in ancestry.com back through the Mainwaring lines to the ancestors of Edward I. Mary's father was Robert Abell b. 1605 Stapenhill Derby England. Robert was son of George Abell and Frances Cotton. Frances was daughter of Richard Cotton and Mary Mainwaring. Mary was daughter of Arthur and Margaret. This will lead you to half of England, Scotland, Wales, Spain and France! I'll swap data??
