Church records in Maryland seem to have the opposite with respect Johann George Gump (aka "George Gump") as well as old Maryland history books. Who can tell when everyone has the same name? Pennsylvania birth records in York County also have George Gump married to Rosina Mack as having earliest record of children by that name. Unfortunately, data is in a box on the moving truck and I can't reference book, page. We can trade and sort this out, if you like.
