Seeking Sparling gravesites

My father's Palatine Sparling ancestors  spent about 150 years or 7 generations after 1707 when they were settled around Limerick Co . Some at Adare, some at  Rathkeale on Dunraven property. They intermarried with resident Irish (Hewson, Doyle, Belton, Printer, Wyndham ) and other Palatine immigrants (Cornelius, Dulmage, LeGier, Shier). They were middleclass protestants, but could have married non-protestants. I have a Sparling family tree on Myheritage.com. The Sparlings came to southern Ohio to settle 1845-82. I am going to tour Ireland in June and then come around Adare and Rathkeale and Limerick for a few days in July to try to find graves or records for the Sparlings and geneology records for the non-Sparling inlaws. I am trying to learn more about Ireland to understand what happened to them after they came and then why they left-I think they may have been in fear of starving on both occasions. We defintely have bred in some Irish characteristics into the steadfast Germanic character-love to sing, dance, write poetry, grow things, hard working, good looking, love freedom, hard to rule. It is really hard to catch the complicated Irish story in an abbreviated  trip. I am an 82 year old university Biology professor retired after 40 years, trying to learn everything I can on this short trip. Mary Lee Sparling PhD
