Mr. Bennett,
My listing has Mary Harper (Hill) listed as being born circa 1730, and Mary Ann Garland being born in circa 1750. Forgive me, I am only using the Mary Ann Garland listing at this point in time, so that is all the information I have available at present.
If you have more information to provide, I would be happy to look it over and make appropriate adjustments to the parts of this tree I have access to.
Thank you for you message,
Raschel Garland
