Am planning a trip to Ireland in the fall and wondering where to start to get the most of family history research. My brick walls are Great Grandfather William Kaley and his parents in Kinsale, Cork - religion maybe Free Baptist? Father was John and mother Katherine Jeah or Jaye. Wm. born March 1844. Wm. emigrated to Lowell, Massachusetts via New York and England, then settled in New Brunswick, Canada.
Other brick wall is Antony Dempsey and wife Letitia Quinn from either Offally or Wexford. They emigrated to New Brunswick, Canada in 1825 with five children, they were probably married about 1800 to 1803.
My head is swirling from irish research sites and want to focus on most effective places to go.
Thanks very much for any help.
