Looking for information on the following surnames: John Mattingly who married Ann Carbery November 1803 in St. Mary's County. My brickwall is what happened to John Mattingly as Ann was a widow in DC by 1820. They had a son, John Mattingly, and I don't anything about him except for the fact he was deceased at the time of his mother's death in 1855. Neither of the John Mattingly's is buried with Ann Carbery Mattingly in Mount Olivet Cemetery in DC. Any help would be greatly appreciated. Best regards, Elizabeth Culhane Fairport, New York
