Does anyone know anything about a Thomas Langdon around 1818 or so? He received a land grant (military bounty) in 1818 from James Monroe, president. It was in twp 6-N. I don't know what township that is. I am researching John Langdon of Monmouth, Warren Co. and am wondering if there is a relationship between these two Langdon's. Thanks, Sharie Oceanside, CA
