William Francis Thomas Butler, Confiscation in Irish history… (1917)
“ The Earls of Ormond and the Earls of Kildare still maintained shadowy claims to great tracts from which all the settlers had been expelled by the Irish. Thus in the time of Henry VIII. the right of the Crown to Connaught was legally beyond a doubt. No Connaught landowner could have a valid title unless he could show a grant from the Mortimers or the De Burgos, and unless the descent to him had been in accordance with the Common Law. [5] There can have been but few landowners in Connaught who fulfilled both these conditions. ”
