How many Realtors out there are also Geneology buffs? In my spare time - well, when I can find some that is, I try to do Geneology research for my family. It's time consuming so I don't get much done!
There is a site called Find a Grave. It's interesting in that you can also look up famous people. You can also sign up to be a photo volunteer, where you go to a grave at someone's request (usually someone out of state) and take a picture of their loved ones grave for them. Sounds eerie to some but you get legitimate requests. Sometimes a family member just wants to be sure where the person is buried before traveling a distance to come visit.
You can leave notes, family photos, along with "virtual flowers" on a grave. Stop by and check it out!
