Broken but still mostly legible, except where the stone has flaked away toward the right. We are almost certain of the surname “Henry,” because the stone lies near several other members of the Henry family. Here is how we reconstruct the inscription:

[In]
MEMORY OF
Elizabeth Hen[ry]
who departed t[his life]
June 10th 1839 in t[he –]
Year of her a[ge.]

—

Esteemed Deaugh[ter,]
this silent grave
Love and respect [?]
shall ever have.

This epitaph, such as it is, seems to be an original composition; Father Pitt has not found it anywhere else on the Web. The spelling “deaughter” is not unusual for Western Pennsylvania tombstones.
