Breen, Keane, Mahony and Young Ancestors From Aghavallen

I'll be heading over soon from Annapolis, Maryland, USA to further my research into my father's maternal grandparents, all of whom are from this parish. They all left North Kerry in the 1890's and ended up in Chicago, Illinois, USA. 

My father's grandmother was Elizabeth Breen (1876-1956), the daughter of Eugene Breen (1846-1882) & Margaret Keane (1844-1884). She was orphaned at age 7 along with 2 brothers and 3 sisters (Pat, John, Mary, Kate and Nellie), whose age ranged between 4 and 11 years ago. They were living in Ballylongford when their parents passed.They were taken in by relatives in Lenamore and Lisroe (Duagh Parish) until they reached the age of 17. I will be visiting Margaret Breen in Lenamore to help sort through the tatters of their story. 

Elizabeth Breen married George Joseph Young (1869-1922) in Chicago, Illinois, USA. He was the son of George Young (1835-?) of Reenturk & Mary Mahony (1839-1926) of Saleen. It appears that all of the significant religious events involve St Mary's RC Church in Kilnaughton Parish in Tarbert. George Joseph Young also had 2 brothers and 3 sisters (Charles, Michael, Mary, Jennie and Annie). All migrated from Ireland to the States in the 1890's. All except for Charles, who went to Ohio, USA, they all ended up in Chicago, Illinois, USA.

I do need more help with my father's maternal grandfather's side of the family. I have found most of the St Mary's RC Church records, Griffith's Valuation and a number of Petty Sessions Court records (that make me smile). Here is the marriage record that can help in the further search:

Marriage of GEORGE YOUNG of REENTURK and MARY MAHONY of SALEEN. St Mary's RC Priest: REV. Dan FOLEY. Fathers: Charles Young (Reenturk) & Michael Mahony (Ballybunnion). Witt: Robert Quinn & Michael McCarthy. Record: KY-RC-MA-77744.

Any help would be greatly appreciated. Include in the help any suggestions on a week long stay for one, along with a car rental spot, in either Tarbert or Listowel. I believe that all of the places that I could visit for family reasons are within an 8 mile, 12.9 km circuit. 

Thanks in advance,
