The Thwaites business was founded by Aynsworth Thwaites in about 1760 and traded as Aynsworth & John Thwaites when father and son were in partnership.

John Thwaites traded under his own name from circa 1780 until 1817 when he took his wife’s nephew, George Jeremiah Reed, into partnership. The Thwaites and Reed business continued into the late 20th century.
