Sir Eubule Thelwall (c. 1562 – 8 October 1630) was a Welsh lawyer, academic and politician who sat in the House of Commons between 1624 and 1629.He built the house of Plas Coch and on 28 December 1607 he received a joint grant of the office of Prothonotary and Clerk of the Crown in Anglesey, Carnarvonshire, and Merionethshire for life, in reversion after the death of Richard Fowler.In 1622, he succeeded in securing a new charter and statutes for the college from King James I, having spent £5,000 on the hall and chapel, which earned him the title of its second founder.He was re-elected MP for Denbighshire in 1628 and sat until 1629 when King Charles decided to rule without parliament for eleven years.[2] Thelwall never married, and left his estate (Plas Coch in the parish of Llanychan, Denbighshire) to his nephew John.
