 Following his decease, his son was never summoned, nor was his grandson, on whose death while still a child in 1347 the right to the barony would have fallen into abeyance between his two sisters Margaret and Isabel.Only fourteen years later, the death without issue of Margaret's sole son and heir John St. Philibert "alias" St. John in 1361 resulted in the termination of the abeyance in favour of the remaining sister, Isabel Poynings, née St John, whose husband Lucas de Poynings was summoned in 1367/8, presumably in her right.At the death of the fifth baron, Thomas Poynings in 1428/9, the barony fell into abeyance again among his granddaughters and their heirs.
