Brow could be an Anglicisation of the Manx Broogh meaning a steaply sloping place. This was a ubiquitous element which entered into dialect speech. Any idea of where in Rushen the place was - i.e. was it on the edge of a steeply sloping piece of land?

No specific place name listed by Kneen, but could someone check in Broderick?
