Check out this ornate tombstone at Copps Hill Burying Ground in Boston, Mass.:
Here is a close-up of the top portion:
What’s confusing is that the top portion claims it belongs to the tomb of Samuel Winslow. The bottom portion states, however, “Here Lyes the Mortal part of William Clark, Esq.” The rest of the lower portion is hard to read in my photo and there appears to be some damage to the text anyhow. The photo on FindaGrave isn’t much better.
I sure would like to know how these two gents were related.

Hmmm. Perhaps Samuel Wilson was a slave of William Clark (though quite an elaborate grave for a slave) – or he was “owned” in some way. So interesting!! What was the year?
According to Historical Marker Database, the tomb of William Clark was later taken by Samuel Winslow, who had his name carved on the gravestone.
