Ahascragh & Killosolan R.C. parish records from 1840 to 1880 are on LDS film number 989756 which you should be able to look at at your local LDS family history centre. [I think a copy is held permanently at the one in London where I looked at it.]
I ordered several LDS films in the hope of seeing the tithe applotment book for the civil parish of Killosolan but it wasn't on any of them. Eventually, I got the page with the townland I was interested in [Loughaunboy] from the East Galway Family History Society and found out why I had been unable to find the right film. It seems that Killosolan may have been included in the parish of Castleblakeney at the time of the tithe applotment books although it was a civil parish in its own right by the time of Griffiths Valuation. The LDS have the tithe applotment books on 140 films. They are arranged alphabetically by civil parish for the whole of Ireland. Film number 256580 has parishes from Cashel to Castleconnor. Film number 256563 has parishes from Aglish to Ambrosetown and MAY include Ahascragh.
