I neither want nor deserve to be pre-1500 certified. However:
Please remove Avice Wallop-3 (1416-1474) as wife of William Blake-301 (1438-1474). The difference in ages make thus marriage vanishingly unlikely. Furthermore I believe Avice Wallop-3 is a mistake for Allice Wallop-2 who was the mother of William Blake-301. See the recent answer to my previous G2G question.
