The subject is identified by family tradition. The original portrait is known only from a 1750s copy painted by John Wollaston. The original likely hung at her home at Turkey Island. Elizabeth Beverley was the daughter of Peter Beverley and Elizabeth Peyton Beverley. She married William Randolph II of Turkey Island. There is a possibility that this portrait represents Mary Isham Randolph (Mrs. William Randolph I).
