Thanks all again for your help. I have now narrowed it down so that IF my John Killoughery (whose birth or baptism I still cannot find!) had a brother named Michael then he can only be the one born 3 Sep 1859 with his baptism in Liscannor (Carrowduff). Another baby of same parents Andrew was baptised Oct 1868... cannot find his birth registration either!). Michael married Mary O'Loughlin in about 1889/90 (no record to be found)
Their parents are Michael Killoughery (c1825) and Honora Foley (c1829) who we would have expected to have married pre 1859 (again not to be found, assume living, marrying and having earlier children elsewhere?). Honora died in 1891, aged 62 and in both census dad Michael is living with son Michael. Again cannot find his death after 1911 either, other than a possible workhouse death 1913.
Richard, sorry I didn't respond earlier... so you are the 2nd cousin to Rita, who is a friend of mine that I am helping with her tree. Rita is here in Lancs but is in touch with her Irish family. If you would like to contact her let me know.
So many elusive records.
Apologies of I haven't responded to anyone but I assure you I read and investigate them all

Thanks
Heather
