This is almost certainly Agnes (Aggie) Morecock, one of the famous Morecock
sisters of Williamsburg, surrounded by her mandolin and guitar students in the yard
of the Bland-Wetherburn House (Wetherburn's Tavern) late in the 19th century. Parke
Rouse, Jr. erroneously calls her Pinky (Elizabeth) Morecock in the caption to
another photograph of her taken in the same location.
