O'Brien Ancestors of Nobber/Cruisetown, County Meath

My husband and I will be celebrating our 10th anniversary in Ireland in July 2020 and look forward to learning more about our ancestors. My 3rd GGF, John Patrick O'Brien was born in Nobber about 1801 and was baptized on 09/02/1802. His mother's name may beMary Hammel. He married Emily Salee (1817-1891) in Tipperary on 11/26/1835. Theirchildren include Thomas Patrick O'Brien (1845-1925), who was born in Liverpool, Lancashire. The family emigrated to Ohio in the US. We appreciate your time and efforts in discovering any research which confirms this family history, as well as any additional information you might discover.
