Apparently named after William, son of George IV, after a royal visit in 1821. This begs the question: What was it called before that? There must have been a native Irish name. Unfortunately Price provides no answer to this in PNCW. On the map of Wicklow contained in Wright's A Guide to the County of Wicklow (1827) this area is named Commons B.nulty, i.e. Commons of Ballynulty, which is a sub-division of the townland of Annacrivey. Since Prince William's Seat and Knocknagun they are only separated by a small saddle, it is possible that the name Knocknagun was applied to both peaks, but this is only conjecture.
Prince William's Seat is the 402nd highest place in Ireland. Linkback: https://mountainviews.ie/summit/352/
