Marriage of Richard Donough, b. 1815 to Letitia ?, b. 1820. Left Ireland abt. 1834 for US, Canton, Massachusetts where my GGrandfather James N. Donough (Donagh) was born in 1836. His brother John was born in Ireland in 1833 before they left for the US. Any help would be greatly appreciated. I have always been told we were from the Isle of Man. Thanks, Don Ballard
