I would like to share something with people who may not know this:There is an ask a grave web site out,and it is free.They have people who will check out these places for you if you can give them some of the details.
It is very hard for a person to go thru a cementary looking for one stone.You really should call the cementary that you think they are in before you send someone out.
Get directions for someone who is willing to do this.Get a list of cemenatary and just call and they will tell you if they are there.
It is that simple.If you know where they lived,try close to home that newspaper.Then find out where they were buried then call to find out directions.This is really important.
Getting a picture is so much easier if you do that.
