Yes. I do have an Elizabeth Greencorn in my genealogy database that was born 07 Feb 1833 in Guysborough county. She married John Adam Knowland (last name Knowlan was also used) John Adam Knowland was born 21 May 1830 in Guysborough county and died in about 1918. They were married in about 1852 and I have 10 children of theirs in my database. In birth order, those are Martha, Abigail, Alfred, Caroline, Lydia, John, William, Jane, David, and Minnie. All born in Phillips Harbor. Let me know if you would like to share genealogy information. I believe your Greencorn relatives are somehow related to mine, but I have not (yet) been able to make all of the connections to the Greencorn families that resided in Guysborough county. I believe your Elizabeth Greencorn was the daughter of John Greencorn and Ann Dort, Both of Guysborough County.
