Summary: In 1770, Joseph Tatnall, a prominent Quaker merchant in Wilmington, hired James and William Marshall to construct a mill race on the north bank of the Brandywine. The Marshalls could not finish the race due to extensive rock in the area, so Tatnall and his son-in-law, Thomas Lea, took over the contract.Tatnall and Lea built several mills below the Market Street Bridge in Brandywine Village. They furnished large supplies of grain to colonial soldiers during the Revolutionary War and also traded flour and corn to the West Indies.
