Hi there, I live in Kingston near Rathdrum in Co. Wicklow. Kingston House was the residence of Thomas Mills King, and the house was the seat of Wicklow at one point. There are no graveyards around that area at all (Kingston) as for a church, there was a church on the estate of Avondale which was probably used by them. There is an old graveyard outside Rathdrum called Kilcommon, but it is more likely that gentry were buried in bigger towns, like Parnell was buried in Glassnevin.
