John fitz Thomas1

He was feudal Lord of Connello and in right of his wife, Lord of Decies and Desmond.2 Tradition says he had four (possibly five) illegitimate sons by four different mothers, three of whom he made knights by virtue of his royal status as a Count Palatine, though other sources say they were knighted by King Edward III at the Battle of Halidon Hill . The knighthoods probably became hereditary by long usage because the heads of these junior branches of the Geraldine family were almost always so created on an individual basis.2
