I record the data on the headstones and provide this information to Find a Grave. I began cleaning up forgotten cemeteries in 2004 and I can't remember how many I have cleaned up. I no longer clean forgotten cemeteries but, I have only began collecting the headstone data for the past few years. The information in my database is showing very interesting information. Most recently, I have been learning the art of headstone conservation and restoration. If I am a memorial manager of a relative of yours, simply let me know and I'll transfer management to you.
