Grave of "an Amiable Child"
New York, New York
This is one of only three private graves in Manhattan. St. Claire Pollock, described on his tombstone as "an amiable child," died at age five, in 1797, probably when he fell off of the nearby cliffs onto the rocks down by the Hudson River.
A hundred years later, former president Ulysses S. Grant died, and his massive tomb -- another private grave -- was built across the street.
