LLOWDDEN HEN of UWCH AERON
By Darrell Wolcott
There were at least 4 men named Llowdden in a family line descended from Llawr ap
Aelan ap Alser ap Tudwal Gloff, all of whom named a son Rhys, and 3 of those Rhys named a son Ieuan. This extended family
includes many men called Ieuan, Ieuan Fychan, Ieuan Llwyd, Ieuan Blaene and Ieuan Fwya. (Blaene means "first or foremost",
while Fwya simply means "again")
The earliest notice of the first Llowdden was in 1168, when the Brut reports "Gwrgeneu,
abbott of Llwythlawr, and Llowdden, his nephew, were slain by Cynan ap Owain".  This Cynan was one of the eldest
base sons of Owain Gwynedd, whose mother was a niece of Bradwen ap Mael of Meirionydd. Due to the relative ages of the
men involved, Cynan's dispute may have been with Llowdden, a man near his own age. The abbott would have been past age
70 in 1168 and may have given Llowdden sanctuary and then was killed for interfering. He is sometimes called a "lay
abbot" so perhaps he was not confirmed by the Catholic Church and not universally recognized as a holy man capable of giving
anyone sanctuary. Llowdden would have been a man in his 40's, so he was not called "Hen" for living a long life, but
simply to distinguish him from a grandson, also named Llowdden.
Llowdden Hen had been born c. 1125 and resided in the commote of Pennardd, cantref
of Uwch Aeron, in Ceredigion. Since the lands which Tudwal Gloff owned in southern Wales were all thought to have been
in Dyfed, there may have been a non-cited marriage among his recent ancestors which brought Llowdden to Ceredigion. The earliest
cited marriage among his descendants occurred two generations later, between cousins. His grandson, Llowdden ap
Rhys ap Llowdden Hen , married Sian (c. 1195), daughter of Gruffudd ap Llowdden Hen. 
That second Llowdden, born c. 1185, lived at Garth in the parish of Llanddewibrefi,
also in Pennardd commote. Citations  call him Llowdden Llwyd y Gath, meaning "gray cat", but do not explain why.
He named his only son Rhys, thus yielding the "Rhys ap Llowdden ap Rhys ap Llowdden Hen" cited by Peter Bartrum in his PP
#38.  The third Llowdden was also directly descended from these first two, being a man born c. 1345 as "Llowdden
ap Ieuan Llwyd ap Ieuan Fychan ap Ieuan ap Rhys ap Llowdden y Gath"
The fourth man of the name was born c. 1215 and is the "Llowdden ap Iorwerth ap Gwrgeneu
ap Uchdryd ap Aleth also cited by Bartrum in PP #38.  The "Aleth" in his ancestry was a brother of Iorwerth ap Uchdryd,
father of Llowdden Hen. This Llowdden was the ancestor of the Rhys Fongam III mentioned below.
There is another name, Rhys Fongam, which is repeated 3 times in this extended family.
Bartrums's charts only identify two such men. Rhys Fongam I of c. 1250 had a father named Rhys, while Rhys Fongam II
of c. 1305 was a son of Ieuan Fychan. The third Rhys Fongam was the son of a different Ieuan Fychan, and lived a full
generation later, born c. 1345. Bartrum's charts conflate him with Rhys Fongam II; his only known descendants
were the Sadler family, whose timeline does not fit with Bartrum's presentation.
A chart of the extended family looks like this:
(a) This is the Llowdden called "the gray cat"
who married a grandaughter of Llowdden Hen. He also married, as his second wife, Lleuci (1185) ferch Gruffudd
(1157) ap Lord Rhys.

Hen (1130) ap Hywel (1100) ap Maredudd (1065) ap Bleddyn (1025) ap Cynfyn. 
(c) He was the son of the 3rd Llowdden in this
family. He married, first, Marged (1260) ferch Gruffudd Foel (1230) of Castel Odwin ap Gruffudd (1195) descended from Gwaithfoed
of Meirionydd.  He married, secondly, Catryn (1250) ferch Maredudd (1215) ap Owain (1185) ap Gruffudd (1157) ap Lord

was Gwenhwyfar (1305) ferch Gruffudd Fychan (1270) ap Gruffudd (1240) ap Ieuan (1210) of Overton.  Also refer to
the Appendix for more about her family.
(e) He married Gwenllian (1290) ferch Elidyr
II (1255) ap Elidyr (1225) ap Rhys (1190) ap Gronwy (1160) ap Einion (1130) ap Llywarch (1100) descended from Pasgen of Gower.
(f) He had a daughter, Gwenllian (1335) who married
Rhys (1320) ap Llewelyn (1285) ap Rhys Chwith (1250) descended from Peredur Beisgwyn of Meirionydd. 
(g) He married a daughter (1360) of Rhys Ddu (1330)
ap Llewelyn (1300) ap Cadwgan (1270) ap Cadifor (1240) ap Rhys (1205) ap Rhydderch (1175) ap Cadifor (1135) ap Dyfnwal
(1100)  He had a daughter, Mabli (1380) who married Cadwgan (1365) ap Hywel (1335) ap Hywel (1305) ap Llewelyn (1275)
ap Hywel Gethin (1245) ap Llewelyn y Moelwyn (1210) descended from Llewelyn ap Cadwgan ap Elystan Glodryddd. 
(h) He was the ancestor of David Sadler (1470)
ap Gruffudd (1440) ap Ieuan (1410) ap Griffri (1380) ap Rhys Fongan III (1345) 
Born c. 1095, this Gwrgeneu was the son of Uchdryd ap Aleth and the brother of Iorwerth, the father of Llowdden Hen.
Various academics read the "Llwythlawr" as a place-name and identify it as "Ludlow". We believe it means nothing more
than its literal meaning "of the tribe of Llawr".
Dwnn i, 243 cites this marriage
Pen 128, 694a calls him Llowdden Llwyd, while a second mention in column "b" of the same page calls him Llowdden y Gath.
The latter form is used on page 737b of the same manuscript
Journal of the National Library of Wales, vol XIII, 1963, page 114. Pedigree 38 (2)
ibid. Pedigree 38(4) which incorrectly makes Uchdryd and Aleth men of Tegeingl attached to Edwin. Many pedigrees
confuse all the Dyfed men named Uchdryd with Edwin's son of that name

Pen 138, 490 cites her marriage to Griffri (1290) ap Rhys Fongam (1250) ap Rhys (1215) ap Llowdden (1185). On his chart
"Llowdden 8", Bartrum identified her as a much later lady: Gwenhwyfar (1415) ferch Sir Gruffudd Fychan (1385) ap Gruffudd
(1350) ap Ieuan (1320), and made her the wife of a Griffri ap Rhys Fongam II who he has dated c. 1370. Our chart in
