File NLW MS 1952B - The History of the Gwydir Family

The Wynn family of Gwydir claimed descent from Owain Gwynedd's second marriage, to Christiana daughter of Goronwy ap Owain ap Edwin, lord of Englefield. Maredudd ap Ifan (c. 1460-1525) of Cwm Penanmaen, Dolwyddelan, bought Gwydir from Dafydd ap Hywel Coetmor. Humphrey Wynn ap Maredudd of Cesailgyfarch, his son, was the first of the family to use the name Wynn. John Wynn (c. 1553-1626) was created a baronet in 1611. Sir John was a member of the Council of Wales and the Marches, deputy lieutenant of Caernarfonshire and twice sheriff of the same county. His son Sir Rchard Wynn became treasurer of Queen Henrietta Maria's household. His grandson, Sir Richard Wynne (d. 1674), 4th baronet, was succeeded by his daughter Mary, his sole heiress. The baronetcy passed to a cousin, on whose death it became extinct. In 1678 Mary Wynne married Robert Bertie (1660-1723), 1st duke of Ancaster and Kesteven, and carried the Gwydir estate into that family.
