Families covered: Princes of Gwynedd, Princes of North Wales, Family of Castellmarch
[Much of this page was originally in Wales03 but was moved here to facilitate expansion after the original Wales01 was renamed Welsh04.]

Sources vary as to the titles given to some of the people mentioned on this page: "King" is used by some whilst "Prince" is used by others. We have yet to adopt a standard policy on this (should such a thing be possible), and have yet to check properly that we are being 'correct' on the regions over which the leaders claimed control, and so may be inconsistent on how we describe them. We will review this in due course.
Merfyn (Mervyn) 'the freckled', King of Powys, Isle of Man & Gwynedd (d 843-4)
As reported on the continuation, Griffith shows the wives of Merfyn and his father Gwyriad the other way around, with Essyllt as wife rather than mother of Merfyn and Nesta as wife rather than daughter-in-law of Gwyriad. Provisionally we follow those sources (such as Wikipedia) which show Essyllt as mother of Merfyn and Nest(a) as his wife but we may review this in due course.
The disagreement between sources on this matter appears to be quite well known. For example, BLG1952 (Phillips of Cilyblidd) quotes Sir John Edward Lloyd, who gives Nest as wife of Mervyn and Ethyllt as his mother, as saying in his 'History of Wales' that "This account, harmonising as it does with Harl, MS. 3859, is to be preferred to the common one, which reverses matters, making Nest the Mother of Merfyn and Ethyllt or Esyllt his wife". Nevertheless, BLG1952 then goes on to show Nest as mother and Essylht as wife of Mervy(n).
