Llewellyn I, Ap Iorworth: he descends from the ancient Princes of North Wales (earliest known ancestor is Llewellyn, Prince of N. Wales, d. 994) and from Aelfgar (Edgar), Earl of Mercia who was banished in 1058 (d. 1059), and his wife Alfigifu (their
dau. Editha m. Griffith I, Llewellyn's son & heir). He recovered his paternal lands in 1194 and in 1201 was the greatest prince in Wales; in 1215 he took Shrewsbury; his rights were secured by special clauses in the Magna Charta. In 1239 he retired to
a Cistercian monastery. Ernst-Friedrich Kraentzler, "The Ancestory of Richard Plantagenet and Cecily de Neville..." (Salt Lake City: Accelerated Indexing Systems, 1978), p. 25, gives Llewellyn's birth year as about 1164. He is known as "The Great".
Professor Stewart Baldwin discusses Llewellyn's ancestry in "The American Genealogist" for October, 2001.
