Levans Family

I'm trying to trace my ancestors and I have a Parish Register for my 2nd great-grandmother, Margaret Anne Levans. She had her baptism at Murroe, Boher and Abington, Limerick and Tipperary, Ireland on March 4 1841. Her parents are Cath Murphy Conor Levans (Is Conor short for Cornelius by chance). Parish Variants: Abington, Boher, Murroe, Murroe and Boher

Anyway, I am trying to find more information on her parents. If this is were the blessing was, wouldn't have live nearby? I'm hoping to find a marriage certificate or something to help continue the path. 

Any help would be greatly appreciated. 

Thank you
