Boyle/McHugh marriage 1870s

[Gortinanima]

John Boyle of Aghakillymaude, Derrylin married a
Rose McHugh possibly from Killesher and had issue
a Hugh Boyle 24 June 1878 in Aghakillymaude, Derrylin,
Fermanagh.

I cannot find the marriage of John Boyle to Rose McHugh
on the Irish civil marriage index but would guess thet were
married c. 1875/6 [as Hugh was supposedly eldest son]. Is there
anyone familiar with the registers of Killesher Catholic
Church as I think the marriage was probably recorded there?
