TUDOR ROSE ~Catherine Woodville, sister of Henry VII.'s wife Elizabeth of York, and her husband Jasper Tudor, Earl of Pembroke, uncle to Henry VII.It was thanks to Jasper that Henry acquired the tactical awareness that made it possible for him to defeat the far more experienced Richard III at the Battle of Bosworth Field in 1485.
Edmund Tudor was Margaret Beaufort's second husband, and father of her only child, Henry. Henry became Henry VII, the first Tudor monarch, so you could say that Edmund was the grandfather of the dynasty. He was born around 1430, and died in 1456, as a prisoner of the Yorkists. He was supposed to wait a few years before consummating his marriage with his child bride, Margaret. He didn't, and Margaret was only 13 when Henry Tudor was born.
