Margaret Strachan (1747–1821) was the daughter of William Strachan of London Town in Anne Arundel County, Maryland. In 1772, she married Thomas Harwood, who served as treasurer of the Western Shore of Maryland from 1776 until his death in 1804. Although undated, this work was probably executed prior to the Strachans’ marriage. It appears on a “payment due” list compiled by Peale for the period 1770 to 1775. A companion portrait of Thomas Harwood was painted around 1775 and is now in the collection of the Winterthur Museum in Delaware.
