Jean Balfour was Scottish and married her Virginia-born cousin, John Blair (1732-1800), in Edinburgh while he was visiting in 1756. Her husband, John Blair, was the son of John Blair, son of Archibald Blair. The artist appears to have signed and dated the portrait in 1776. However, the portrait looks heavily overpainted. The artist worked in Virginia in 1770-1771.
