I am the 11th. G. Grandson of George Martin and Susannah North-Martin. I am also the administrator of the vibrant Facebook group: Susannah North-Martin Legacy. All descendants of George Martin, (first wife Hannah), and/or Susannah North-Martin are invited to join. Simply go to FB and under "Find a Group" type: Susannah North-Martin Legacy. We are a descendants group with many expert genealogists to help with your research.
Note: The correct birthplace for George Martin is ROMSEY, HAMPSHIRE, ENGLAND not Ramsey, or Cambridgshire England as many have in their genealogies.
I also have connections to the Weed family of Salem/Danvers, MA
