Yet, a third suggestion is that 'Rowallan' is of Brythonic or Cumbric origin, especially in that this area of Scotland lived under these languages for over a thousand years before Gaelic began to take hold. Broken down, 'Ro' is the equivalent of the Welsh “Rhy” (even the Old Irish 'Ro') meaning 'too' or 'very', while 'wallan' closely mirrors the 'wallon' suffix so often seen in Welsh and Old Breton, which derives from guallaun, or ‘good/best'.
