My husband's GGrandmother Bridget Dobbin married Thomas McHenry (both 20 years old at the time) in Ballymather on June 21, 1885. Thomas's father's name was James McHenry and Bridget's father's name was William Dobbin. The witnesses on the marriage certificate were James McHenry and Elizabeth Magill. Marriage took place at Crumlin Roman Catholic Church in Crumlin. Let me know if there could be a connection.
