This is so true, especially with cemetaries, because alot of them could be very hard to read, which leads the author to guess the spelling by reading other markers around that one. But as you said, everyone is subject to human error. These are still great books, but should checked out with several other avenues. Also, bear in mind, that I, too (although rarely)LOL am subject to human error. If I give you information that doesn't quite match up with what you already know, ask me to recheck, because it is very likely that I could have typed something in wrong or read someone else's dates. We're only human! Kristy
