Bonedd y Saint

The Bonedd y Saint or Seint (Welsh for "Descent of the Saints") is a Welsh genealogical tract detailing the lineages of the early British saints. There are a number of different manuscripts in existence dating from the early 13th to the late 17th century, although the material is much older in origin.^[1]

The book has also been known as Achau Saint Ynys Prydain ("Genealogy of the Saints" or "Pedigrees of the Saints of the Isle of Britain").^[2]
