Gleeson family

My 3x great grandfather was William Gleeson, born 1823 in Borrisokane, Tipperary.  He was married to Martha "Mathilda"  McIntyre, born about 1823. They came to the U.S. with children William and Ellen.
I believe that their elder son, Roderick, stayed in Ireland.  I think that Rody may be the person that is listed in the census in Youghalarra, Tipperary in 1901 and 1911, and who died in Nenagh in 1914. I would like to find out if that is my Roderick, and if he had descendants who were in Ireland, and where they ended up.
I found on the map from Griffith's, the small house and land that William Gleeson rented in 1852 in Borrisokane.  I would like to know more about the area, and I am planning to visit there this July.  Any assistance would be greatly appreciated.
Thanks, Eileen Flinn Burton
