I have also been having a hard time finding Greencorn descendants. I have an Elizabeth Greencorn who I am guessing was born around early 1830's. She married John Knowland and the children I know of are Lydia Knowland and Abigail Knowland. Both daughters married Rhynold's. I have yet to find the birth date/ place, death, parents and so on of Elizabeth Greencorn. All surrounding descendants have been from Philip's Harbor, Guysborough NS.
