The first line:
"Peace to the spirits of my honoured parents, respected be their remains, and immortalized their virtues! may time, while it moulders their frail relicks to dust, commit to tradition the record of their goodness; and Oh, may their orphan-descendant be influenced through life by the remembrance of their purity, and be solaced in death, that by her it was unsullied!"
