Sir John Duckworth, 2nd Baronet
Sir John Thomas Buller Duckworth, 2nd Baronet was a British Conservative politician.
Duckworth was the son of his namesake John Duckworth and Susanna Catherine Buller. He married Mary Isabella Buller, daughter of John and Harriet Buller, in 1850, and they had three children: Mary Georgiana ; Evelyn Harriet ; and, Fanny Catherine. He inherited the baronetcy of Topsham in 1817 on the death of his father.
Duckworth was elected Conservative MP for Exeter at a by-election in 1845—caused by the death of William Webb Follett—and held the seat until 1857 when he did not seek re-election at that year's general election.
