William ap Rhys

There are many sites which refer to a person listed as the son of Katherine Howard and Sir Gruffed ap Rhys ap Thomas 1508. I would point out that That William was born 2 years before Katherine Howard was married to Gruffed and their first child was Griffeth not William....So who is William? William ap Rice 1521/22 is the son of Daffid and Beatrice  ap Rice who are 3rd cousins to Gruffids family, and likely fostered little William Henry Rice while they served in the household of Princess Mary Tudor 1520-1558. The fact that William Henry was granted a Coat of Arms with the Pomegrannite same as Mary's Mother Kathrin of Castile, is a CLUE as to his parentage....Gruffed would have been age 14 when William Henry was born, and Since William's sister Mary was born 1528 she would have been listed as an heir to Katherine Howard's estate, and she was not listed nor was William....Burks peerage does not list William Henry 1522 as a natural sonne of Katherine/Gruffed ap Rhys.
