Dooish overlooks Lough Beagh and the Glenveagh National Park. Divis Mountain, overlooking Belfast, shows a different anglicisation of the same name. It is also possible that Dubhais is itself a re-interpretation of an earlier name, especially as other colours do not appear to combine with ais in hill -names. Something akin to Welsh diffwys meaning ‘steep slope’ or ‘desolate area’ would seem apt both for Divis in the Belfast Hills and to Dooish in Glenveagh.
An Dubhais is the 195th highest place in Ireland. Linkback: https://mountainviews.ie/summit/187/
