Every so often, a figure from the margins of the historical record steps forward with more depth than expected. William Blethyn — Bishop of Llandaff from 1575 until his death in 1590 — is one of those people. He isn’t a household name, but when you tug on the threads of his story, you uncover a man working at the fault lines of Welsh identity, Tudor statecraft, and the long, stubborn memory of lineage that culminated in the William Blethyn Pedigree Roll.
Blethyn was born at Shirenewton Court in Monmouthshire, and his family traced descent from Hywel Dda, connecting him to a storied Welsh lineage. He was related to Morgan Blethin, abbot of Llantarnam in 1532. The records are shy on details, as usual for the sixteenth century, but he appears to have come from a clerical or minor-gentry family rooted in Monmouthshire1. His education at Oxford — sources variously name New Inn Hall or Broadgates Hall2 — before taking clerical posts in both Berkshire (Rector of Sunningwell) and Monmouthshire (Rector of Rogiet). He later earned a Bachelor of Civil Law and held a prebendary at York Cathedral (Osbaldwick) before returning to Wales1.
Blethyn married Anne Young, daughter of a Welsh family connected to Thomas Young, later Archbishop of York. She died in 1589, and Blethyn remarried another Anne later that year1. These familial connections reinforced his social and political position in Elizabethan Wales.
Bishop of Llandaff
He was consecrated Bishop of Llandaff on 17 April 1575, under Archbishop Matthew Parker and during the reign of Queen Elizabeth I. The see was notably poor, and Blethyn was granted dispensation to hold multiple church livings in addition to the bishopric1.
Historical sources describe him as a capable administrator, a firm disciplinarian, and a determined opponent of recusancy (those refusing to conform to the Church of England). He issued episcopal statutes to govern the cathedral chapter, defined the roles of canons and vicars choral, and protected cathedral documents and property1. He also took a practical interest in the cathedral’s physical fabric, ensuring its maintenance during a time when many bishops were primarily symbolic figures.
Death and Burial
Blethyn died on 15 October 1590 and was buried at Mathern Church, Monmouthshire, where he had resided. Notably, no monument survives to commemorate him1.
Children and the Pedigree Roll
The William Blethyn Pedigree Roll traces his lineage and descendants, providing insight into both family memory and Welsh dynastic identity2.
Sons
- William (married Elizabeth, daughter of Thomas Morgan of Tredeger)
- Philemon (no wife listed)
- Timothy (no wife listed)
Daughters
- Anne (married Richard Thomas of Berthily)
- Rebecca (married Renault Gwen of Pyldy/Pwll Du)
- Jane (married John Thomas)
- Sara (no husband listed)
Cross-referencing the roll with primary sources such as his will (proved 1591) confirms nearly all these children and some additional details3:
- Philemon later became a clergyman, marrying Susana Godwin in 1610 and serving as vicar of Dorstone, Hereford. There are some interesting tidbits about his son Theodorus and father-in-law, Francis Godwin, that I may explore at a later date (a possible connection to Jonathan Swift)4.
- Timothy appears to have entered a more modest profession as a carpenter5.
- Anne, Rebecca, Jane, and Sarah are all explicitly named in the will, confirming the roll’s accuracy3.
- William’s wife, Elizabeth Morgan, aligns with the roll’s note of her being the daughter of Thomas Morgan of Tredeger3.
Legacy
William Blethyn’s legacy is one of pragmatic leadership, careful administration, and family continuity. His children’s lives demonstrate both social mobility and the challenges of maintaining status across generations. For historians, the combination of the Dictionary of Welsh Biography, the pedigree roll, and the bishop’s will provide a rich view of a Welsh churchman navigating the complexities of the Elizabethan era. For someone living on the edge of an empire, that is a legacy with surprising reach.
