I noted Irvilloughter is a townland in the parish of Ahascragh Co Galway. Is that correct?
Couldn`t find a Michael Kelly birth for your date on
www.brsgenealogy.com. It is worth looking at that site though for BDMs that may prove relevant to your search-just remember to click on Galway East on the map as there`s a separate part of that site dealing with galway west. Also if you wish to view a transcription you`ll have to pay 5 euro-even if the record turns out to be the wrong ancestor.
Griffith Valuations were taken in that part of Ireland in the 1850s. On
www.failteromhat.com there are two Michael Kellys for Ahascragh-though not Irvilloughter.
Kelly Michael Cloncannon (Dillon) Ahascragh Galway
Kelly Michael Kilglass Ahascragh Galway
The 1901 census on
www.leitrim-roscommon.com also shows a Michael Kelly ages 82 (a lot of them guessed their age though) with his wife Bridget and family living in Ahascragh.
Yes, clutching at straws indeed but maybe you`ll find the above websites helpful for your research anyhow.
