Thomas Smith RIC posted to Wicklow 1870

I am looking for info on Thomas Smith Sub inspector RIC. He was posted to Wicklow in 1870 from Dungannon co Tyrone. He retired about 1876 and lived inDublin in 1884. I am trying to find out where in Wicklow he lived. Two of his children were married at churches in co Dublin Kilternan and Dun Laoghaire, so I think that Thomas may have been near Bray. I am trying to find if his wife Frances Jane Mooney died when he lived in co Wicklow and where she is buried. Thank you
