The Henniker Baronetcy, of Newton Hall in the County of Essex, was created in the Baronetage of the United Kingdom on 2 November 1813 for Brydges Henniker, who had earlier represented Kildare Borough in the last Irish Parliament. He was the youngest son of John Henniker, 1st Baron Henniker. The sixth baronet was an admiral in the Royal Navy and sat as Conservative member of parliament for Galloway. The eighth Baronet was a brigadier in the Royal Engineers.
As of, the Official Roll considers the baronetcy dormant.[2] Adrian Chandos Henniker, presumed 9th Baronet (born 1946), succeeded his father in 1991. He has no heir.
