Margaret Ellen Parker, born Dundalk 27 Jan 1830, married Patrick Henry Gilmartin there on 28 Feb 1854 [many thanks to all friends who sent me this info]. I assume they emigrated, and the only 1830 Margaret Gilmartin I have found in US Census had Bridget in 1850 and Catherine in 1852 (variously in Ireland or New York depending which Census you read). Seems unlikely, somehow, these 2 girls were born out of wedlock and later 'adopted' by a Scripture Reader! Were Margaret and Patrick married in a conventicle back in, say, 1849, and they got the marriage properly registered at St Nicholas Parish Church, Dundalk, only in 1854? Or, perhaps, was Margaret already a widow by 1854 - can anyone tell me if the reg entry says?
BTW, is it likely that someone called a Scripture Reader at marriage would thereafter in successive New York Censuses be merely 'laborer'?
