I live in Delaware County, PA and regularly visit a few local cemeteries, especially Arlington (Drexel Hill) and Fernwood (Lansdowne). I also volunteer with the Friends of Mount Moriah Cemetery and take photos there when I can.
My own research includes the following surnames: Warner and Felver in New York and New Jersey, Hess and Hill in Ohio, Rulon, Bolesta, and Marnie in Pennsylvania (Philadelphia area) and New Jersey.
Please feel free to use my photos for your family tree. Credit is always nice.
