Hello Jeanne, My Thomas, the pilgrim and husband of Ann Heilson/Helsdon had three children. They were Thomas Jr., Elizabeth and Peter. Thomas' daughter married Edward Fitzrandolph. I know of no Zachariah Petty. My lack of knowledge doesn't mean that a Blossom did not marry a Petty. I only know the marriage you mentioned was not my Thomas Blossom's daughter Elizabeth. Wish I could help more. Bill Marshall
