Michael Shaughnessey has written an interesting article about the disappearing graveyards of Pittsburgh, Pennsylvania. The limited flat ground in that mountainous town is often re-purposed. By looking at old maps, one might find that their favorite store, athletic field – or even their own backyard – are the final resting place of even relatively recent (19th century) immigrant ancestors.
Some of my departed Keating ancestors died while living in Pittsburgh. I’ve never made it up the relatively short distance to visit their grave-sites, but now I wonder if it would even be possible.
