Meurig may have¹ married off several of his daughters to the sons of king Emyr Llydaw from Armorica, who left their homeland to settle in Glamorganshire after the usurpation of the crown by one of their brothers*. These marriages are said to have produced many of the early Welsh saints, making Meurig's family one of the great centres of Welsh church mythology*.

As an afternote: Miles Salley, one of the Bishops (1500-1517 CE*) buried in the church, left instructions to have his heart buried next to Tewdric*. When Bishop Godwin had the grave at the high altar of the church opened in 1610 a stone coffin and an urn, said to contain the heart, were found*. Godwin wrote in 1614 "I discovered his [Tewdric's] bones...the skull retaining the aperture of a large wound which appeared as if it had been recently inflicted."* The remains were reburied, only to be re-exhumed and re-interned in 1881 during the restoration of the church*.
