Dorothy, Purdy is my direct line. I have a James H. Purdy b. 1802 Westchester Co. White Plains NY to Henry Purdy and May Calhouhn or Colurn, but do not have a marriage for him or children. James siblings were Henry 1800, Alexandria 1796, Jacob1794 m. Esther Searles, Ann 1792. Hope this can help. Bev
