Callaghans/Buckleys

Looking for information for the family Callaghan from (Lisleagh), Ballyclough, Cork. William Callaghan (my 3x grandfather--1805-1875), his wife Margaret Buckley (1818-?), and daughter Ellen Callaghan (1840-?).  Their son Michael (1838-1926) --my 2x grandfather- emigrated to the US in 1858--landing in Mobile, Alabama--fought in the American Civil War (1862-1865) -- moved/lived/died in East Liverpool, Ohio--Married Mary Desmond in 1865, also from Ireland. I found the Callaghan homestead, which is still standing in Ballyclough! I used Griffiths Valuation. I cannot, however, find where William and Mary are buried! Or any other information about their lives there in Lisleagh, Ballyclough. Or any information about Williams' parents:  Patrick Callaghan (b. abt 1774) and Mary Collins.  Any help would be greatly appreciated! ~Kelly Callahan
