Anne, I am looking at the same edition (2009) that is cited on the profile. Page 473 does have the PURCHASE family. It has Oliver PURCHASE and Thomasine HARRIS (d. 1577, Dorchester, Dorset) at the top of the tree. The only children it then lists are Aquila PURCHASE, married to Ann SQUIRE, and Joan PURCHASE, married to Bernard CAPEN. It does not list John or any other children. The book only traces the lines of presidents and these two had three presidents among their descendants. Aquila had Millard Fillmore, and Joan had Ulysses Grant and Calvin Coolidge.
