I do not have a personal interest in the following - I post it only because I have made contact with a few DOLAN researchers with ancestors in this cemetery.
The following was published in our church bullentin last Sunday:
St. Denis Cemetery, Located in Havertown, Delaware County, PA, is seeking families who may have a cemetery lot in out cemetery, but who have "lost contact" with us. If you, or some of your relatives, or friends, every had family in the Havertown, Oakmont South Ardmore or even the West Philadelphia area, there may be a family cemetery lot at St. Denis.
