I am researching the Irish lineage of our family and have traced to James Moore b. 1829 in Ireland according to the Marriage Register - he married Sarah Jane Graham (b 1838 in Ontario, d 1907 Ontario) on 24 March 1859. I believe that HER father is also from Ireland - John Graham, b 1806 and d 1880 Canada.
As regards John Graham, he appears as a son of Ann Brunty and James Graham per Catholic Parish Registers in Anacorra/Killavany, Ferns diocese. Not positive if this is the same John Graham, but it's some of the only that I've found that matches. Have also been limited in my discoveries on James Moore as there are many names to sort through with little data/
