Elizabeth Branch was born in North Carolina in about 1733. In 1755 she married Edward Underhill, who died in 1758. Later Elizabeth married John Green, a prominent carpenter and joiner in Edenton. Elizabeth likely co-managed her husband's inn or tavern in Edenton and also helped care for the couple's two daughters as well as several apprentices that her husband had live with them while they trained to be craftsmen. In 1774 she became a signer of a non-importation agreement that later became known as the Edenton Tea Party Resolves. She survived her husband, who died in about November 1779, but the precise date of her death has not been located.
