Do you know anything else about the Leers? I am descended from Leonard Leer b.1773 in Hesse Cassel, Germany d. 1826 bet. Maryland and PA of murder. I am descended from his son Michael Leer b 1813 in PA d. 1900 in Pa. I'm sorry I don't know anything about your Peter, but I would gladly appreciate your help if you know anything else about the family. They are from the Adams/York/Cumberland county area as well
