My great-great grandfather was Isaac Watson Coghlan who was married 3 times. His first wife was Phebe Watkins(1811-1858)and they had 10 children: Emily Ann, Henry, Margaret, Phoebe Jane, James, Rebecca, John, Emeline, Isaac Watson (I'm assuming JR.), and Julia. His second wife was Mary Ford, they had no children. His third wife was Lydia Easton and they had 6 more children: Joseph, Charles, General McClellan (my great grandfather), Mary, Daniel and Gideon. Does any of this help? I have more info on G.M. Coghlan if you want it.
