LLOWARCH AP BRAN - A PEDIGREE WITH PROBLEMS By Darrell Wolcott
Many leading families of Anglesey trace their descent to this early twelfth century nobleman but the pedigrees they cast contain an abundance of misinformation. Most of the errors and omissions stem from like-named men who have been confused with each other, and this is true even for his ancestry from Tudwal Gloff ap Rhodri Mawr. Both our work and that of noted Welsh genealogist Peter Bartrum point to a birthdate near 1120 for Llowarch.
PROBLEM # 1 - The ancestry of Llowarch:
Tudwal Gloff was perhaps the youngest son of Rhodri Mawr, too young to have taken part in the battle when his father was killed in 878, but received the leg wound which accounts for his nickname "the lame" in the 881 "revenge of Rhodri" battle of Conwy. A birthdate near 865 is indicated since no boys younger than 15 were sent into battle. If Llowarch ap Bran were born 255 years later, he would be in the 8th following generation, not the 6th as shown by many pedigrees. We believe the descent was as follows:
865 Tudwal Gloff
960 Alser *
*Most extant pedigrees skip from this Alser directly to Tudwal Gloff
Our insertion of Dyfnwal ap Alser in the pedigree is based on citations which say Gronwy ap Tudor Trefor married Tanglwst ferch Dyfnwal of the line of Tudwal Gloff. One calls her "ferch Dyfnwal ap Aelan ap Alser ap Tudwal" but that would date the lady 50 years later than Gronwy ap Tudor Trefor who was born c. 940. Making Dyfnwal a grandson of Tudwal Gloff dates her to c. 955; thus we believe the missing generations in the pedigree of Llowarch ap Bran are those shown in our chart above.
It would appear that land is all that the son of Tudwal ap Rhodri obtained in Dyfed, and Tudwal (being lame) expected nothing more.
 Burke's Commoners, vol iv, pp 381 says "Tudwal espoused Helen, daughter of Aleth who, in the genealogies, is styled brenin Dyfed". It was Hyfaidd who was king of Dyfed at the time Tudwal Gloff would have sought a wife, and we believe Aleth was a younger brother of that king. The male name "Aleth" occurs often among families descended from Tudwal and is unknown in other families. Tudwal's lands were in Rhufoniog in Gwynedd but two early families said to descend from him are found in Dyfed, suggesting he did marry a lady from south Wales. He was only a half-brother of Cadell and about a half-generation younger.
THE LEGENDARY KINGDOM OF SEISYLLWG
By Darrell Wolcott
Tudwal, King of Dyfed; he was wounded in the knee by the Saxon king Adewal, at the battle of "Rhodri's Revenge," and afterwards became Chief Justice of Gwynedd. [Welsh Founders of Pennsylvania II:48]
Tudwal Gloff, or the lame, so called from the effect of a severe wound in the knee, which he received at the battle of Cymryd, a place within two miles of the town of Conway. In the third year after the death of Rhodri, the Mercians, encouraged by their former success, again invaded North Wales, but being met at the place last mentioned by Anarawd, the young reigning prince, his brother Tudwal, and their forces, the Angles suffered a signal defeat. Prince Anarawd ordered this decisive victory to be chronicled under the appellation of "Gwaith dial Rhodri," i.e. Revenge for the death of Rhodri. Tudwal, for his general good conduct and bravery in this battle, was rewarded by the diademed princes, his brothers, with an additional grant of lands in Uchelgood Gwynedd, and the lordship of Ceredigion, or that western tract lying between the rivers Dovey and Teivy.
Tudwal espoused Helen, daughter of Aleth, who in genealogies is styled "branin Dyved" (Demetia). [History of Commoners IV:381]
TUDWAL (GLOF,) or the Lame, one of the sons of Rhodri Mawr. He fought under his brother Anarawd at the battle of Cymryd, on the Conwy, in A.D. 880. against the Saxons, and in a personal combat with Eadred, Earl of Mercia, he was wounded in the knee, on account of which his brother gave him the monasteries of North Wales. (Greal, 120.) [Enwogion Cymru pg449]
