Last week Megan and Jim Heyl were kind enough to do some cemetery sleuthing for me. In spite of the rude and unhelpful attitude of the office staff, they found the groundskeeper to be helpful. He located the sod covered headstones of my paternal grandparents.  The Heyls dug them out and replaced them on top of the sod so that they are now showing. More on Detroit Memorial Park Cemetery in the future.
