My Condon Ancestors

Good morning!  My great grandmother, Ellen Condon, was born in Kildorrery and baptised on June 2 1866.  Her parents were Richard and Catherine Condon, but I haven't been able to definitively go any farther back than that.  I do not know where Richard and Catherine were born, but I believe they may have been cousins because in their marriage record, Catherine's father was listed as Timothy Condon.  I think maybe Catherine's mother was a woman named Ellen Lee.  And somewhere in Richard's family there was a Redmond Condon (perhaps Richard's father).  I say this because Ellen's son (who was my grandfather) had the name Albert Redmond.  I am hoping to definitively determine Richard and Catherine's parents (and maybe even THEIR parents as well, and to find out if, indeed, they were cousins.
