My grandmother name was Geneviena (Vivea) Pieper and she married Dennis(Dan)Heck. My father's name is Gerald Joseph Heck. If your great grandmother was Charlotte Lilly Pieper then she was my 1st cousin twice removed. The only reason Iknow that is they have a family history on Peter Pieper (isn't that funny) and Maria Elizabeth Kotter and Their Descendants and my dad got it for me for Christmas.Mr Edward H Moore put it together and it is really interesting. If u want to order one they are available.
