# Ellis ap Griffith

Ellis ap Griffith (c.1440 – 1489) or Elissau ap Gruffudd, was the Baron of Gwyddelwern in Denbighshire, Wales, and the grandnephew of Owen Glendower, Prince of Wales. Following his family defeat during the Glyndwr Rising, his branch inherited the co-representation of the Royal House of Mathrafal, and were immortalized by William Shakespeare in the history play Henry IV. Through his mother Lowrie, he inherited the lordship of his grandfather, Tudor Glendower, and by marriage, the estate of Plas-yn-Yale. By this union, he became the founder of the House of Yale, represented by the Yale family, later known in America as the benefactors of Yale University.

## Biography

Ellis ap Griffith was born circa 1440, in Corwen, Denbighshire, to Griffith ap Einion of Corsygedol and Lowrie ap Tudur of Gwyddelwern, members of the Royal House of Mathrafal and the Ducal House of FitzGerald. His father Griffith ap Einion held the office of Woodward of the commote of Ardudwy, Merioneth, under the Lancastrian Henry V of England, and was proprietor of the Corsygedol estate, in his family since the 13th century. His grandfather was Lord Tudor Glendower, son of prince Gruffudd Fychan II.
His uncles were Ieuan ap Einion, 5th Baron of Edeirnion, and Howel Sele, of the family of Hywel Sele, 9th Lord of Nannau. His mother was first married to Robin ab Gruffydd, Lord of Rhos. Their family later married with the Lords of the Nannau estate, near Dolgellau, which has been in their possession for over 900 years, allying the descendants of King Bleddyn ap Cynfyn, founder of the House of Mathrafal, and rival of William the Conqueror.
His granduncle Owain Glendower, Prince of Wales, and other family members, launched the Glyndwr Rising against the Lancasters, in alliance with their kinsmen; the Percys, Mortimers, and Tudors of Penmynydd. Having lost the last Welsh War of Independence, Ellis's family were either killed at battle, imprisoned, or merciless put to death, and lost much of their estates and castles.
His mother Lowrie inherited the royal claims after the fall of the Royal House of Mathrafal, and transmitted to Ellis the lordship of Gwyddelwern from his grandfather. His family would later be featured in William Shakespeare's play Henry IV, Part 1 and Part 2, along Shakespeare's Henriad, with his granduncle being the rebel character Owen Glendower.
The Tudors of Penmynydd, their cousins through Tudor ap Goronwy, were also defeated, and a member, Owen ap Maredudd, emigrated to England and took the name of his grandfather, becoming Sir Owen Tudor, first of the House of Tudor. He married the widow of Henry V, Queen Catherine of France, and became the grandfather of the first Tudor monarch, Henry VII of England, father of Henry VIII. Owen Tudor was Ellis's second cousin, and Henry VII, Henry VIII, and Elizabeth Tudor were third cousins.
Ellis ap Griffith succeeded his grandfather's lordship, holding the title of Baron of Gwyddelwern, and held the office of Raglot of the commote of Penllyn, and Juror of the county of Merionethshire, under the Yorkist Edward IV of England. Ellis is also recorded in documents relating to the endowment of Cymer Abbey, which was committed to his charge and to Edmund Beaufort, Duke of Somerset, from which Sir Thomas Stanley, Chamberlain of North Wales, requested payment of debts and revenues for the region of Merionethshire.

## House of Yale

Ellis ap Griffith founded the House of Yale circa 1480, when he married Margaret, daughter of Jenkyn of Allt Llwyn Dragon (Dragon's Grove Hill), renamed Plas-yn-Yale. Through Ellis's mother Lowrie, the Yale family became cadets and co-representatives of four royal houses as co-heirs of Prince Owain Glyndwr, last Welsh Prince of Wales, along with the Hughes of Gwerclas. The name was adopted from the Lordship of Yale, previously the commote of Iâl in Welsh, which had belonged to his mother's family through four subsequent royal families, being those of Cunedda, Gwynedd, Dinefwr, and Mathrafal, since the foundation of the Kingdom of Gwynedd by their Romano-British ancestor Cunedda, its founding King in late Roman Britain. By this union came the usage of the Yale name as a surname, adopted from the maternal side, a practice that was adopted later by Chancellor Thomas Yale, first of the name.
The Lion of the Kingdom of Powys, the emblem of Mathrafal, inherited from the Princes of Powys Fadog, Lords of Yale, is featured as the Black Lion on Ellis's coat of arms. Ellis bore both the arms of Gwyddelwern as Baron and heir of his grandfather, Lord Tudur ap Gruffudd, and those of his father Gruffydd ab Einion (Vaughan) of Corsygedol, which was inherited in the male line from Osborne Fitzgerald of the Fitzgerald dynasty, through the branch of the Lords Desmond, later Earls of Desmond. Osborne was an Anglo-Norman who descended from Gerald de Windsor of Carew Castle, son of the 1st Governor of Windsor Castle for William the Conqueror. He came from Ireland to Wales during the middle of the 13th century, and was granted estates and arms by the Prince of North Wales, Llywelyn the Great.
Over time, the Yales married with their cousin branch, the Hughes of Gwerclas, and other noble houses of Britain, such as the Cavendishs, Dukes of Devonshire, and the Norths, Earls of Guilford. Lord North of Wroxton Abbey, the British Prime Minister who lost the American War of Independence under his term, was a cousin. Thomas Yale of Plas-yn-Yale married the daughter of the 14th Baron of Cymmer-yn-Edeirnion, and their daughter Dorothy Yale, married the 16th Baron. In the early 19th century, Sarah Yale, head of the House of Yale, and last of the direct male line, died without children. As an heraldic heiress, the Plas-yn-Yale estate and coat of arms were entailed in her will, making Lt. Col. William Parry-Jones, her cousin, the new heir general of the House, and exchanged by Royal licence 1867, his name and arms for those of Yale, becoming Lt. Col. William Parry Yale.
His nephew, Oxford lawyer William Corbet Yale, succeeded him, and also inherited Widcombe Manor and Madryn Castle from his cousin, Sir Thomas Love-Jones-Parry, son of Lt. Gen. Sir Love Jones-Parry. He was also of the family of Admiral Robert Lloyd, who fought against America and brought back to England the body of Maj. Gen. Sir Edward Pakenham, the brother-in-law of the Duke of Wellington. His heir was Oxford lawyer John Edward Ivor Yale, son-in-law of Sir Henry Lewis of Belmont, and member of the family of William Debonaire Haggard and the Haggards, who were admirals and bankers in the City of London. As of 1969, the Yales were still featured as members of the British nobility in Burke's book of the landed gentry, and in 2021 died from this branch Queen's Counsel David Yale of Snowdonia.
