Joe, I just had a lady email me a portion of the book The Old North Esk written by W.D. Hamilton. He was a professor at a University in NB and operates Miramichi Books. In his book, he lists a John Ahearn probably from County Cork. and his wife Ann Meighan who married in Newcastle in 1827. in 1850 they settled at South Esk. Baptism records for his children include a Michael c 1830 who married a Mary Ann Fortune. At this point, I am atttempting to locate a place to purchase the book and then trying to find the churches and prove any of this information... Jean AHearn
