My great grandfather Matthew Hart was born in Ireland about 1844. His parents were Peter Hart (b abt 1821) and Ann King (b abt 1822). They were married, I suspect, about 1841. They had another child Catherine Hart about 1845. The family emigrated to England about 1846.Matthew was 2 & Catherine was 1.They were Roman Catholic. Can anyone verify that they were from CO Louth?Any way to search RC Church records?Thanks.
