I also have a RIENHART/RINEHART in my tree. Here is what I know: "Big George" Stonerock married Margaret RIENHART on November 22, 1819 in Pickaway County, Ohio. According to the 1820 Ohio Census for Pickaway County, George and Margaret are listed as being over 45 years of age. Robert A. Stonerock "We all take different paths in life, but no matter where we go, we take a little of each other everywhere" - Tim McGraw
