Naval power

The triads give some indication of the naval powers at the time. Triad 14 mentions the Seafarers/Fleet Owners. Geraint ab Erbin and March ap Meirchion were both of Cernyw. There must have been frequent communication between this kingdom and those of Brittany for the LL to regard them as “one people and one language”. Triad 15 gives the Roving Fleets and Bromwich suggests the names may indicate they were Irish while those of the previous triad were British[1]. It may be that with Tintagel being on the north coast, the Cornish and Irish together controlled all trade going through the Irish Sea. Likewise Dumnonia and Brittany could have dominated commerce through the English Channel.

The regnal list of Glywysing

The kings of Glywysing were descended from King Arthur as indicated by JC20 12:

Gen. JC20 12a seg.
13 Morgan Hen
12 Owain
11 Hywel
10 Rhys
9 Arthfael
8 Ceingar
7 Maredudd
6 Tewdws
5 [Rhain]
4 Cadwgon
3 Cathen
2 Gwlyddien
1 Nowy
0 Arthur
-1 Pedr
-2 Cyngar

Morgan Hen died in the year 974. The LL tells us:

Morgan Hen son of Owain, King of Glamorgan, contemporary with Edgar, King of England …[1]

Edgar died a year later in 975. The father of Morgan, Owain, according to the ASC, accepted Athelstan as overlord in the year 926. Arthfael’s father is given by JC 9 as Gwriad ap Brochwel. His mother, Ceingar from Dyfed.

Sanan ferch Elise


HG 15 states:

[G]ripiud . Teudos
caten . Tres sunt
filíí nougoy .
et sanant elized .
filia illorum . mater erat
regis pouis

Bartrum originally interpreted this slighlty corrupted text correctly thus:

… tres sunt filii nougoy regis pouis, et sanant filia elized illorum mater erat.[1]

This is shown int the table below where the generation numbers have been allocated:

Gen. HG 15
9 Gruffudd Tewdws Cathen
8 Nowy Sanan
7 Elise

JC 8 has:

Gruffud. a thewdos. a cathen. Meibyon y vrenhin powys. o sanant verch elisse y mam. Elisse. verch neuue hen mab tewdwr.

The full pedigree list in JC 8 is:

Gen. JC20 8
13 Tewdwr
12 Griffri
11 Elise
10 Tewdwr
9 Gruffudd Tewdws Cathen
8 Vrenhin Powys Sanan
7 Elisse
6 Tewdwr
5 Rhain
4 Cadwgon
3 Cathen
2 Ceindrech
1 Rhiwallon
0 Idwallon
-1 Llywarch
-2 Rhigeneu
-3 Rhain Dremrudd
-4 Brychan I

Y Cymmrodor XLIII 57

Comparing the two tables above, the ruler of Powys, Vrenhin Powys, in gen. 8 is clearly a reference to a Nowy, Sanan’s husband indicating Elisse verch Nowy Hen is an error and that Elisse was the son of Tewdwr. In fact, Elise is a male name.

Note, Rhain Dremrudd is an interloper in this pedigree as he was a contemporary of St. Cadog. Tne cognomen Dremrudd has been incorrectly attached to Rhain ap Cadwgan.

Bartrum correctly proposed the idea that Nowy, the husband of Sanan, was the son of Madog using the lineage that appears in JC 16:


Gen.  JC20 16b seg.
14 Lleucu
13 Adwent
12 Eliffer
11 Gronwy
10 Cynhaethwy
9 Ceno
8 Nowy
7 Madog
6 Sandde
5 Tudwal
4 Merin
3 Madog
2 Rhun
1 Cenelaph Dremrudd
0 Cynan
-1 Casanauth Wledig Thewer
-2 Brydw

Cadair Early Series (Aberystwyth University)

Nowy ap Madog occupies gen. 8 as does Nowy in the firs table and  Bartrum’s proposal was sound. Unfortunately, however, he abandoned this idea, as can be seen by his crossing out in this chart:

He tentatively adopted Dumville’s incorrect proposal that Elise, not Nowy, was the king of Powys and that his father was Gwylog who appears in HG 27 and on the PE.[2] In this scheme Nowy, the husband of Sanan, is made the son of Tewdwr ap Rhain, see the pedigree chart below:

Britons and Anglo-Saxons in the Early Middle Ages 51

Dumville’s chronology does not work. He suggests Tewdwr ap Griffri was a signatory of a land charter dated 934. In fact the LL states this individual was Tewdwr ab Elise.
