It has been suggested (without proof) that Guy III de Brian (born c.1202) was the son of Alphonse de Brienne (born 1178) and grandson of Jean de Brienne (born 1148, see BRIENNE COUNTY) but this overlaps two earlier Guy's in Devon

King Henry I encouraged settlers from Devon and Somerset to moved into South Wales, and also placed groups of Flemings into the centrefs of Rhos and Daugledday. The Flemings built castles and founded communities, with Flemish names. The aim was to swamp Wales with pro-Norman supporters, to reduce the chances of a rebellion succeeding.

[BRIA371] Guy I de Brian of Torbryan (Devon, referred to as Torre at the Domesday Survey).

[BRIA381] Guy II de Brian.

[BRIA391] Guy III de Brian adomarus (born c.1202) first appeared in South Wales c.1219. He married [POOL392] Johanna de Pola (born c.1202, see POLA).

Shortly before Christmas 1215, the Anglo-Norman marcher lords suffered after a bloody and devastating 3-years campaign by the Welsh forces under Prince Llywelyn fawr ab Iorwerth. They were thrown out of many of their castles e.g. Carmarthen and Cardigan, and the castles at Laugharne, Llanstephan and St. Clears were wrecked. It was not until 1223 that William Marshal the younger, 5th Earl of Pembroke, recovered Cardigan and Carmarthen, and possibly Laugharne at the same time. It is possible that as a result of this recovery, Guy de Brian was installed at Walwyn's Castle (Pembrokeshire) and/or Laugharne Castle (Carmarthenshire). It is only known that Guy III was in South Wales by 1219, and that his son Guy IV had acquired these castles by 1247.

[BRIA401] Guy IV de Brian (born c.1228), of Walwyn's Castle, married twice.

Sources suggest Guy IV's son & heir was Guy V by his first wife, and that Maud was a daughter by his second wife, based on there usually being more information available about a widow than an earlier wife. However this gives a dating problem, i.e. Maud was (apparently) ten years older than Guy. This may be avoided by transposing the order of the wives, which is here done, which assumes historians are correct in stating Maud's mother was Eve. Therefore, according to this theory, Guy IV married 1. [TRAC402] Eve (see TRACY); then 2. ---. This then leaves the question about Maud being only 14 years younger than her father, but perhaps Guy was born earlier than stated.

Guy received a grant from King Henry III to hold a yearly fair at his manor of Talachar, the former name of Laugharne, (1247). Guy had acquired Laugharne Castle (Carmarthenshire) by 1247, and also Walwyn's Castle (Pembrokeshire). He rebuilt Laugharne Castle which was then in a bad state of repair.

From 1255 the Welsh under [GWYN389] Llywelyn fawr ab Iorwerth were attacking the Anglo-Normans, and around 1257 they sacked several castles, capturing the one at Laugharne and taking Guy prisoner. He was released the following year on payment of a ransom, partly raised by his tenants and partly with a contribution from the king. Guy IV was present at the Battle of Lewes (14th May 1264), and died c.1268.

[BRIA412] Maud de Brian (born 1242, only daughter of Guy & Eve) married 1. [MART411] Nicholas FitzMartin (born c.1236, see MARTIN), died 1260; then 2. (by 1273) Baron Geoffrey de Camville. Maud died 1279.

[BRIA411] Guy V de Brian (born c.1252, son & heir of Guy & his 2nd wife), married Sibyl de Sully. He died 1307. Sibyl died 1st June 1325.
