Isaac Gilbert (1742-1822), a great grandson, served in an American unit of the British army in the French and Indian War and also in the Revolutionary War. He and his family immigrated from Connecticut to Gagetown, New Brunswick in 1783. Descendants lived in New Brunswick, Ontario and elsewhere in Canada. Many descendants immigrated to Michigan, Indiana, Ohio and elsewhere in the United States.
