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 13 June 2007, the presumed ninth and present holder of the baronetcy has not successfully proven his succession and is therefore not on the Official Roll of the Baronetage, with the baronetcy dormant since 1991.
