I am a direct descendant of John Rutherford, Cootehill, Co. Cavan, Ireland. He would have been born about 1795, location unknown. He is my father's 2nd great grandfather. Robert Rutherford, born about 1824 (location unknown but assumed Cootehill), is my father's 1st great grandfather. He stayed in Ireland. Perhaps they all stayed in Ireland and the family that immigrated to Scotland in the late 1840's was not this same family? There are many discrepancies as to what really happened here. I have a baptism record of Martha Rutherford, B1826, Drumgreen (just a kilometer or two outside Cootehill Town), father John Rutherford, mother Rebecca. I have a baptism record of John James Rutherford B1830, Drumgreen, father John Rutherford, no mother listed. I have a Confirmation record for Elizabeth Rutherford, Drumgreen, 1826.
I have several kits on all the DNA websites.
