looking for Donlavy family of Castleconor.  They lived there around the middle of the 18th Century.
Mr & Mrs Donlavy had a child Catherine/Katherine/Kate.  I believe Kate's mother died in childbirth and may be buried in the old Killanley burial ground. Mr Donlavy remarried, inherited some money and became Donlavy-Balfour. 
Looking for inspiration please as I am completely stuck
