My paternal line is Tuttle. There was some confusion over which Tuttle line my branch belonged to so I recently took an FTDNA Y-DNA test to confirm it genetically. We descend from this gent, William Tuttle, b. 1607 in Ringstead, Northamptonshire, England, and d. June 1673 in New Haven, Connecticut, and his wife Elizabeth, b. ~1609, also in England, and d. 31 Dec 1684, also in New Haven. They immigrated to the New World about 1635.
Some concise interesting reading on these Tuttles from the New England Historical Society.
