I'm nothing like a serious student of cemetaries and tombstones, but take the opportunity to browse old sites often when traveling around. Some of us students, in a past life, used to drop by an old cemetary between Clarksville and Russellville, in Arkansas. We always visited the grave of Laura Starr Latta, who died in her teens in the early 1900's. Her inscription, under a carved rose:

       Gentle stranger, passing by
       As you are now, so once was I
       As I am now, so you shall be
       Prepare yourself to follow me.

I think that awhile back several people here noted that the same inscription or some close variant used to be fairly common.
