I am trying to trace a James Henry Mandeville to New Jersey. He died in Ontario (Canada) at the age of 80 in 1876 which places his birth about 1796 in New Jersey according to Ontario death records. His daughter's death record says he was born in Newark. I have found a James Mandeville born in Pompton Plains on Dec 28, 1796 to Henry Mandeville and Fytje Gillalin. Henry is the son of David and Mary (Courter) Mandeville. Therefore, James is the grandson of David and Mary. The question is now whether the two James are the same person. Did the Henry of Pompton Plains move to Ontario with his father or did he stay behind? Is there a different James in Newark born about the same time. Any help would be appreciated. Gordon Hillman
