MARGARE[T]
consort of
ROBERT FARI[S]
& dau of [Arthur & Ann]
Irwin, died Dec. 2, 1836:
in the 30 year of
her age.
There is more of interest on this gravestone: An epitaph is still intact and legible.
When nine years old, she sought the Lord.
Nor did she seek in vain:
According to his gracious word,
He pardon’d all her sin. R.F.
R.F. = Robert Faris? I’d like to think so.
Oak Grove Cemetery, Delaware County, Ohio
