Kilvine records

I wonder if there is any other places I can look for Kilvine, Cllarmorris, Mayo  BMD records.  I have  roots, Ancestry, FMP subscriptions and have used NLI and irishgenealogy.  I can't find RC baptism before 1865 or so.  My g-grandfather Augustine Hu(v)ane was born about 1846 and he married Catherine Scahill from ballydonlon, Dunmore Galway (I have found her baptism in 1853 and 1 sister who emigrated to Australia.  Not sure if there were others. 

Did Kilvine use other parishes or are the earlier records missing or non existent? 

I have all Augustine's children as they were all born in Galway, but I was hoping to find more of Augustine's sibs.  I know of 2 brothers families, Stephen, James and possibly Patrick.  I have been making educated guesses for his sisters, but would love to confirm. His mother was Catherine Heneghan and I think she was also from Kilvine and married Augustine is father, James Hu(v)ane.  

Aprreciate any thoughts , thanks, Mary
