My Kingdom for a sheep?

Fleas can move 1000 times their own weight. The first mechanical clock was 30ft high, water powered and invented in China in 1088. Henry VIII's great-granddad was an Anglesey farmer. Which of the above is false? Answer; none of them! Pause for incredulous laughter. However, Henry VIII's great-granddad was an Anglesey farmer! His name was Owen Tudor and he came from a place called Penmynydd, between Llangefni and the Menai Straits. Let me explain.
At the time of the reign of Henry V, you know, Agincourt and all that, Owen Tudor left Anglesey to better himself and became a squire to the king. The king died in 1422 and some years later his widow, Catherine of Valois, is said to have married Tudor, although it is possible they were never legally married. Henry's infant son, Henry VI, succeeded him. The new king was little more than a pawn in the so-called Wars of the Roses, a series of power struggles between the ruling House of Lancaster and the rival House of York. Owen Tudor was a staunch supporter of the king. In 1461 Tudor led an army into battle against Yorkists forces at Mortimer's Cross in Herefordshire. The Yorkists side won; Tudor was killed; Henry VI lost his throne and the Yorkists claimant, Edward IV, became king. Owens's son Edmund had married Margaret Beaufort, who was descended from King Edward III's son John of Gaunt, the Duke of Lancaster. Edmund died while Margaret was pregnant with their first child, Henry, who was born on January 28, 1457 at Pembroke Castle in Wales. At first Henry was kept hidden in Wales by his uncle, Jasper Tudor. In 1471 Henry VI died - he may have been murdered - in the Tower of London, and Henry Tudor became the Lancastrian claimant to the throne. In 1483 Edward IV died suddenly and his young sons, Edward V and Richard, "disappeared" in the Tower of London. Their uncle, who had imprisoned the boys, swiftly crowned himself Richard III. Not surprisingly, he was an unpopular king. In 1485 Henry Tudor returned to Wales, raised an army, invaded England, and defeated Richard III at the battle of Bosworth Field. Richard died in the battle, and Henry Tudor became Henry VII, the first Tudor king. And his son, HenryVIII succeeded him! So there you have it, and not only that, the farm's still there although unfortunately not open to the public. It dates from the 16th century, having been rebuilt when the family fortunes took a sudden upward rise. I wonder why?
