I know I've mentioned FIND-A-GRAVE before here, but maybe didn't say how it works.
If you're wondering where great aunt Alice is buried or when she died, it's a good place to try. Not every grave in every cemetery is listed of course, but searching by last name/state gives you parameters.
A wonderful service on Find-a-Grave is providing volunteers who'll go to a nearby cemetery and find/photograph graves that others request. That's how I ended up at Oakland Cemetery in Little Falls last Sunday.
No, I didn't find any lost Heschs, but some of those gravestones had familiar names...for instance, three Valentine graves. They had to be the family of Anna Valentine who married John and Ket's son Paul...and, there were names I recognized from the Bohemian church books....and one or two of the Lindburghs are buried there. Still, the coolest part was wandering such a peaceful hillside on a cool fall afternoon, and taking pictures that someone needs.
