Who is this lady?

[RJNorton]

Excellent, Susan! You are correct. Laurie, thanks for such an interesting answer.

The inscription in the question is what Newton Strong asked to be engraved on his wife's tombstone.

John S. Richards, the editor of the Berks and Schuylkill Journal, saddened with the sudden death of 29-year-old Matilda, wrote a notable tribute to her:

"The sudden death of this most esteemed lady has awakened an unusual degree of sorrow in the circle of her friends. Her gentle temper, her conciliatory manners, and the sweetness of her heart made her dear to all who knew her. The memory of such as she cannot perish and it will be long ere her many friends shall cease to think of her virtues and grieve for her early death."
