I was working on a family tree for a cousin and I accidentaly stumbled across this link:
West Laurel Hill Cemetery in Philadelphia's records are online!
It only shows the burial location and a few have dates. This is a big deal because it costs $10/lookup by mail. I checked and my 1/2 great uncle and his wife are buried there and I know where now! He was 30 years older than my grandmother, so we didn't know what happened to him. I was there last year when I lead a private research trip for a client, so now I get to go back and check the flowers that I planted for other cousins.
