Thank you.
"Genealogical Memoir of the Chase Family of Chesham" p7 (George B. Chase, 1869) and "History of Samuel Paine Jr." p61 (Albert Prescott Paine, 1923) combine to show the following descent:
Thomas Chase (lived sometime in the 1400s in Chesham) had a son, John Chase (m. Elizabeth).
They had a son, Mathew Chase (m. Elizabeth Bo(u)ld).
They had a son, Richard Chase (m. Mary Roberts).
Isabel Chase (b. abt. 1545) married Richard Baldwin in Cholesbury. I have found trees that show Isabel(l) Chase as the daughter of Richard and Mary (Roberts) Chase, but I can find no documentation or sources for that relationship.
