Will of Crisp Molineux of Garboldisham proved 16/05/1793. His main heir in tail was his grandson Crisp Molineux Montgomerie (q.v.), who in the event does not appear to have succeeded to Garboldisham or to the St Kitts estates. In the will of his son George Molineux Montgomerie proved in 1804, George commented that his third son Thomas Crisp Montgomerie was well provided for under his grandfather's will, and later that after the death of his second son William, his [George's] father's estates had passed to his [George's] third son Thomas Crisp Montgomerie. He made it a condition of his will that his heirs take the name Montgomerie in memory of his 'good mother' from whom the Crisps estate descended.
