Surnames Kirkpatrick and McEvly

My grandfather x 3, Robert Groghan is buried together with his wife Honoria in the grave of a Kirkpatrick at Fahy Old Cemetery.

From the graveyard subscription I have been given it would appear that the grave has initially been erected by the wife of w Kirkpatrick.  Her name was Alice and before being married she was Alice McEvly.

I can't find anymore details out about w Kirkpatrick apart from the inscription states he died 7 May 1845 and his wife Honoria died 31 December 1893.  I can't find a register of these deaths when I search online.  I am also curious, as Kirkpatrick I have always thought of as a Scottish name and perhaps being more popular around Ulster and with a protestant connection than Co Mayo and I was hoping someone might know more of any Kirkpatricks that lived in Mayo.  As far as I am aware my ancestors in Ireland have always been Catholic so this is a bit of a puzzle to me at the moment.
