Not sure if this is the right place to ask this question, if not let me know so I can repost. Today I was searching out my ancestors in a family plot and came across 3 small headstones next to the main monument. I could make out initials on two of the stones, they were the same initials of 2 of the families children, the third I could not make out. But weird thing is, the one guy is buried in another cemetery, the other daughter was buried with her husband in the same plot with another stone. They did have 2 more children and several grandchildren so the 3rd marker could be anyone. I know of no other children that died young or anything like that. What do these small markers mean? Are they more like a "reservation" thing, as in holding their place to be buried there? Or a way of honoring the dead family members who are buried somewhere else? I've never come across this before where I knew the person was not buried there. Anyone have any suggestions about this practice? The deaths were all in the mid 1800's. Thanks!!!
