the name Margaret Corris caught my attention as I also have Corris from Patrick in my research. Mine had a Philip Henry born c 1852 to John Corris born c 1820 & who md Elenor Callister in Patrick in 1845. In 1841 I have a John Corris aged 45 (the father of the above John) but can't figure out his wife - Nappy ? in 1841 & Esther in 1851, all in Patrick. Maybe they are related to the Corris family you research.
