You know, I got this information from my grandmother's genealogical research, but taking another look at it, I'm not so sure about how accurate her information on Jacob Taylor and Nancy Green is. I haven't been able to find a verification on her information about Mary's parents.
I AM 100% sure that Mary Taylor's parents were named Jacob and Nancy (both from PEI) and that Mary was born in 1789.
If you could send me any of the information that you gathered about Jacob (and Nancy, if you have any), that would be great. Its one part of my family genealogy that is sadly lacking.
