Ronald,
I am very interested in the Kelly's of Balladda. I've tracked the Kelly portion of the family (mother) to John W. Kelly b. 1730 born in Balladda, d. 1820 unsure where. His wife, Elizabeth Harper b.1735 and d. 1819 have not information on where she was born or died. I would be happy to share any of the information I have as it regards to the Kelly's in the United States if you are still interested.
Best Regards,
Jay Todd Cleaver
