GLYN (also GLYNNE ) , family of Glynllifon , Caerns.

Traditionally the family was derived from Cilmin Droed-ddu , who settled in the place after his flight from his native Cumbria in the 9th cent. , and historically from Tudur Goch who for war services under Edward III obtained a grant of escheat lands in Nantlle . By his marriage with Morfudd , another descendant of Cilmin , he obtained Glynllifon , which became the chief seat of his descendants. HWLKIN LLOYD , Tudur 's son, held the town of Caernarvon for the king under William de Tranmere in 1403 , and d. the following year. MEREDYDD LLOYD , his son, was bailiff of Uwch Gwyrfai in 1413-15 , and accompanied some forces sent to protect Guernsey in 1456 . The next heir, ROBERT AP [d. c. 1509 ] was twice m., each wife being a member of English families who administered Gwynedd for the English kings . The first wife was Ellen Bulkeley of Beaumaris , and by her Robert had six sons and four daughters. Two of these sons were prominent clerics in the early Tudor period MORUS GLYN , LL.D. [d. 1525 ], was archdeacon of Merioneth , and WILLIAM GLYN , LL.D. [d. 1557 ], archdeacon of Anglesey . Robert ap Meredydd 's second wife was Jane Puleston of Caernarvon , and the issue of their marriage was known as WILLIAM GLYNNE the Sergeant [of Arms , temp . Hy. VIII], whose son WILLIAM GLYNNE [ fl. 1588 ] m. Lowry , the heiress of Lleuar , and founded the house of the Glynnes of Lleuar . Upon the death of Robert ap Meredydd his estates were divided between two of his sons: EDMUND LLOYD obtained Glynllifon , and RICHARD AP [d. 1539 ] got Plas Newydd and Nantlle . Richard became the head of the family known as Glynns of Plas Newydd and Nantlle . Edmund Lloyd was sheriff of Caernarvonshire , but he d. during his year of office ( 1541 ). He was succeeded at Glynllifon by his son William who became known as WILLIAM . He took a leading part in the affairs of his county , and attained to a prominent position amongst his fellow men. Though not a member of the bardic craft, he was a bard of repute, and served as one of the commissioners in the 1568 Caerwys eisteddfod . He was three times m., and d. in 1594 ; he was buried at Clynnog . THOMAS GLYN [ fl. 1585 ], his son and heir, did not attain the eminence of his father, but he too was included amongst the bards of his days; another son, RICHARD [d. 1617 ], rector of Llanfaethlu , was the ancestor of the Glyns of Ewell , Surrey , bankers . Thomas 's son, Sir WILLIAM GLYN ( knighted in Dublin in 1606 for military services in Ireland ) was highly esteemed in the county, and was reckoned a man of high honour and integrity. He m. Jane , the daughter of John Griffith of Cefnamwlch [see the article on that family], and by her he had six sons and five daughters; he d. in 1620 . His successor at Glynllifon was THOMAS GLYN (three times M.P. for Caernarvonshire ). In the conflict between the Crown and Parliament he sided with the parliamentary party [but see the appended note], and was governor of Caernarvon castle after its surrender in 1646 . He d. in 1648 . His brother JOHN [ 1602 - 1666 ], known as John Glynne the Sergeant ,’ was recorder of London and later Lord Chief Justice , and took a prominent part in the proceedings of the Long Parliament , but after the Restoration he won the favour of Charles II who made him a baronet in 1662 [see Glynne of Hawarden family ]. Sir John Glynne d. in 1666 . His brother, EDMUND GLYNNE [b. 1615 ], was active in the support of the commonwealth, and as J.P. served his county well before and after the Restoration . Thomas Glyn was succeeded at Glynllifon by his son JOHN GLYNNE [ fl. 1644-69 ], who m. Elizabeth , daughter of Sir Hugh Owen of Orielton . There were two daughters of the marriage, FRANCES GLYNNE , and ELLEN GLYNNE [d. 1711 ]. The former m. [ c. 1700 ] THOMAS WYNN of Boduan [ 1678 - 1749 ] [see Wynn of Rug family ], and the surname Glynne was thus lost. Thomas Wynn became a baronet [ 1742 ], and his grandson Sir Thomas Wynn [ 1736 - 1807 ] became the first lord Newborough in 1776 .
