I think I have my Smith's tracked back to John Smith born approximately 1622 in Sudbury England and married to Sarah Hunt in 1647 in Sudbury, Middlesex, MA. John and Sarah had three son's, Thomas Smith born July 1658 in Sudbury MA, John Smith born Jan 1647/48 in Sudbury Middlesex, MA, and Robert Smith born May 1654 in Sudbury, Middlesex, MA.
