Henry was James's stepson, taking the Knevett name on his father's marriage. Lived at Mogden House. Married 1803. He inherited all the family monies and became a the victim of a vendetta, because he was not of the Knevett line. This prevailed until his death. Subject to such embarrassment, in Isleworth, especially at the hands of local residents, he had a "chip on his shoulder" all his life.
