I have conducted quite a bit of research on the Greencorns of Guysborough County. More specifically, I have been focusing on Greencorns that resided in the Philips cove and/or Crow Harbour communities within Guysborough County. Could you provide a rough idea of when the Martha Greencorn that you listed was born or married? I have a Martha Greencorn in my database that was born abt. 1800 and married a Daniel Williams on 21 Jun 1825.
