Looking for Kennedy and Drohan Ancestors

My ggg grandparents, William Kennedy and Brgid Drohan were married at St. Molleran's Church in Carrick-beg; County Waterford Ireland in 1844.
William and Brigid lived in Mayfield (a/k/a Rocketscastle) near Portlaw, and William worked as a gardener at Curraghmore House, Lord Waterford's Estate.
William was the son of Morgan Kennedy; it is though that Brigid's father's name was Michael.
They moved to Hartford, Connecticut USA in 1880.

I have been tested and am L226+ (West Ireland III haplotype.)

I am most interested in contacting possible cousins in Ireland.
Thanks in advance for your help.
