Fielding Lewis (1725-1781) was a wealthy merchant in Fredericksburg. Born at Warner Hall in Gloucester County, he was the son of a prominent Virginia planter, John Lewis. He married George Washington's sister, Betty, after his first wife, Catherine Washington, who was George's first cousin, had died. He had a successful store in Fredericksburg and loaned the government money to build a gun factory during the Revolutionary War.
Kenmore was built by Fielding Lewis and Betty Washington, George Washington's sister, in the 1770s in Fredericksburg, Virginia. The brick mansion is a fine example of Georgian style architecture. Its interior is decorated with neo-classical ornamentations that anticipate design features of the Federal Era. Like Chatham Manor, the house was used as a hospital during the Battle of Fredericksburg in the Civil War.
