A brick wall. I went through the 1790 and 1800 census for PA. Dauphin and Lancaster Co.'s seem to be the location of the GREIDER surname. Is/are there any GREIDER researchers who can assist me with Susan GREIDER. She married abt 1790 to John Phillip CUNIUS. I could use any and all help.Thank you for your time and effort. Take care.
