Dwan in Penders Census of 1659
(www.johngrenham.com)
In a "census" of 1659, 61 inhabitants with the
name of Dwan were counted, mainly in the Munster area, in the
baronies of Kilnamagh (Tipperary) 15, Iffa and Offa (Tipperary)
13, Cosmore and Cosbride (Waterford) 8, Clonlisk (Offaly) 10,
Carbery (Kildare) 9, and Ardmagh (Armagh) 6. It seems likely
that the Duanes of Tipperary town are descended from the Duanes
of Kilnamagh or Iffa and Offa.
