My father's line traces back to the Chases and my records show two Thankful Berrys. One was married to Richard Chase with a son Archelus born 5/17/1807. Information came from WFT Vol 1 tree no. 949. The other married a John Chase, born 4/16/1675, the son of John Chase and Elizabeth Baker. John's brothers, William, Thomas, Captain Jonathan, Jeremiah, and Isaac. Thankful, born 1671-1691, was listed as a Mayflower descendant in 'The Mayflower' Vol 13 page 147. I have no information on her parents. I found information on her from WFT Vol 4 tree no. 651. Hope this helps in your research Holly Snead Snead@bellsouth.net
