Bruach na hAille and Barr na hAille unfortunately seem to be more popular house names, quoth Google.
The house is on the bog, halfway between the top of a cliff and a little river valley, which ends in the sea in a waterfall. Only the cliff and the sea are directly visible. An ancient settlement is nearby.
Between cliff's edge and valley?
Ancient Sea View?
…?
Alliterations preferred.
