Robert Keen (d.1793)
Robert Keen was one of two London merchants to whom Whitefield bequeathed his orphanage at Bethesda in Georgia. A woolen draper by trade, he had been involved with Whitefield's ministry in London since at least the 1760s. A regular correspondent of the great evangelist, he was buried in a vault beneath the Tottenham Court Chapel in London.
