Sir Alexander St. John was born around 1396 in Weobley, Llanrhidian, Glamorganshire, Wales, into a distinguished noble family. He was the son of Sir John (II) St. John, a knight of the Barony of Penmarc and Lordship of West Barry, and Lucy Basset, the heiress of Uchel-olau (Highlight) in Gwenfo, Glamorganshire. His lineage traced back to the powerful de Clare and Basset families, with connections to the Anglo-Norman aristocracy of Wales and England.
Through his mother, Alexander inherited half of Cwmcidy, known as Highlight (Uchel-olau), solidifying his status as a landed lord. He became the Lord of Highlight and was later recognized as a Knight of Uchelolau, a title reflecting his military and feudal standing. His family was associated with the Knights Hospitallers of St. John of Jerusalem, an influential medieval military order.
Alexander married Johanna Craddock (b. ~1412), with whom he had at least two sons:
John (III) St. John (b. ~1428, d. bef. 1473), who inherited Weobley Castle.
William St. John, Esq. (b. ~1440, d. ~1538), who continued the lineage at Highlight Abbey.
As a knight, Alexander likely participated in regional conflicts and served under the English crown during the turbulent Wars of the Roses. His possession of Weobley Castle and Highlight Abbey placed him among the landed gentry of Glamorganshire, where he managed estates and upheld feudal obligations.
Sir Alexander St. John died around 1480 at Uchel-olau (Highlight), leaving a lasting legacy in Welsh and English aristocracy. His descendants maintained prominence in Glamorganshire, with his son William living to the remarkable age of 98, further securing the family’s influence.
Heraldic Visitation (1531): His lineage was recorded in Welsh heraldic visitations, confirming his noble status.
Feudal Records (1429): Listed as a landed gentleman in Glamorgan, holding the fee of Uchelolau.
