Charles Bosanquet was the second son of Samuel Bosanquet of Forest House, Leytonstone, and a nephew of Mary Bosanquet-Fletcher. Bosanquet was a successful businesman who served as sub-governor and then governor of the South Sea Company (1808-50) and from 1823 to 1836 as chairman of the exchequer bill office. He also wrote a series of influential treatises on commercial themes.
In his later years he moved to Rock Hall near Alnwick in Northumberland, which he inherited from his wife's brother. He served as a Justice of the Peace and Deputy Lieutenant and was High Sheriff of Northumberland in 1828.
