General Notes
SOURCES: Ancestry.com/Kirk Larson Ancestry.com/Robert Jones
Robert Jones has "The Six Wives of Henry VIII" by Alison Weir listed as one of his sources. Need to read the book when I get a chance. My grandfather York always told us there was a link to Henry VIII in his family.
I believe that Lettie may be Joan de Damarell of Stoke, born about 1300. She was heiress of Stoke Damarel, Devonport, Devon, England. Some internet sources list Joan as the wife of Roger II de Seymour born 1285. I believe this should actually be Roger III.
Also see Surname "D'Aumerle". Is there a possiblity that Joan/Lettie is the daughter of Geoffrey D'Aumerle of Devon, England?
