Gilbert married Isabel de Beumont in 1130.

Isabel - was the sister to Robert earl of Leicester and Waleran count of Meulan. Isabel had been the youngest mistress of King Henry I, and their liaison resulted in a natural daughter, Isabel (Elizabeth), born c.1129/30. When Isabel de Beaumont married Gilbert in 1130, she took this daughter with her.

Gilbert - - There has been debate about the name "Strongbow" ascribed to both Richard and his father Gilbert. In a charter in The Chronicle of Melrose issued by Richard's grandson, Richard Marshal, both Richard and Gilbert de Clare are named as "Strongbow". The men of Netherwent (Gwent) were known for their skill and use of an unusually long and strong bow; both Gilbert and Richard held the lordship of Netherwent. Since Gilbert de Clare's seal shows him holding a long arrow in his right hand, historians assume that the ability and skill to use this type of bow earned both Richard and his father Gilbert their nicknames.
 
Strongbow's father, grandfather, uncles and great-uncles were men favored by both King Henry I and King Stephen On the death of Roger de Clare without legal heirs in 1130, King Henry I granted Gilbert de Clare his lands of Orbec and Bienfaite in Normandy. With the death of King Henry I in 1135, Strongbow's father, Gilbert, supported Stephen as king, and was an active military commander for Stephen during the "anarchy". When Gilbert's uncle Walter de Clare died in 1138, King Stephen granted Gilbert the lordship of Netherwent, including the castles of Chepstow Castle and Usk Castle. Stephen also granted Gilbert the comital title and lands of the earldom of Pembroke the same year.

Earl Richard - - 6th Earl of Hertford.
 
By the middle of the 13th century Richard de Clare had expelled the Welsh rulers from the western valleys of Glamorgan, as far as the Rhondda, whilst leaving the rest undisturbed.
 
Richard de Clare was a leading member of the reforming party of barons in England. King Henry Iii's personal style of government and his reliance on foreign advisers had antagonized many of the barons who regarded the royal policy as diminishing their own power and influence. Llywelyn ap Gruffydd (d.1282), prince of Gwynedd, exploited this division and dissension amongst the English. On Richard's death in 1262, Llywelyn moved up the Usk valley, capturing the Brecon lands of Humphrey de Bohun (guardian of the young de Clare heir), and reaching the northern edge of Glamorgan. By 1267 Llywelyn had become master of the greater part of modern Wales, except for the southern coastal plain.

i.  Sir Gilbert "The Red Earl" de Clare was born on 2 Sep 1243 in Hampshire, England and died on 7 Dec 1295 in Monmouthshire, England . See #10. below.
----- Seventh Generation -----
10. Sir Gilbert "The Red Earl" de Clare - was born on 2 Sep 1243 in Hampshire, England and died on 7 Dec 1295 in Monmouthshire, England . He was the son of Earl Richard de Clare and Maud de Lacy.
Sir Gilbert married Joan of Acre on 30 Apr 1290. Joan was born in 1272 in Acre, Palestine. She was the daughter of King Edward I "Longshanks" Plantagenet and Princess Leonor of Castile and Leon. She died on 23 Apr 1307 in Suffolk, England and was buried in Abbey, Tewksbury, Gloustershire, England .

Joan - After Gilbert de Clare died in 1295, she married, to her father's great displeasuree, second, Ralph de Monttemer, Earl of Gloucester and Earl of Atholl.
 
She was a remarkable active woman in the dozen years following the Red Earl's death. By the terms of the marriage agreement in 1290 the entire inheritance was enfeoffed jointly on Sir Gilbert and Joan. This meant that it would not be possible for her father, Edward I, to grant her only a third of the estate and control the rest himself during the long minority of their son Gilbert.
 
Joan was thus the sole mistress of the inheritance and she controlled it with remarkable ability. In 1297, much to Edward's displeasure, she secretly married an otherwise obscure knight in her 'familia', Ralph Monthermer.
  Then Sir Gilbert married Alice de Lusignan in 1257. Alice was born about 1240. She was the daughter of Hugh de Lusignan XI and Yolande de Dreux. She died on 9 Feb 1291 in Warren, Sussex, England .

Sir Gilbert - Earl of Clare, Herford and Gloucester.
 
When Gilbert married Joan of Acre, he gave up the inheritance of all his castles and manors in England and Wales to her father, Edward I, for him to dispose of them as he saw fit. Edward settled them on the issue of the marriage. Gilbert built Caerphilly Castle, in Glamorgan, which can still be seen and visited.
 
Gilbert "the Red" as he was known after the fiery color of his hair - was to become involved in the turbulent English politics of the 1260s. At the time of his father's death Gilbert was a minor, though he was given possession of the Gloucester estates in 1263. To begin with, Gilbert continued in good terms with his powerful neighbor, Llywelyn ap Gruffydd. However, over the next few years a series of military and political events was to completely change this situation; the building of de Clare's masterpiece Caerphilly Castle,
 
See Caerphilly Castle
 
By 1287 Gilbert de Clare had cleared the road to Brecon and had begun another castle on his new frontier at Morlais near Merthyr Tydfil. Here he came into conflict with Humphrey de Bohun (d.1298), the earl of Hereford, who disputed possession both of the land and the castle at Morlais. Earl Gilbert was to experience further difficulties just a few years later. In the autumn of 1294, the Welsh broke in revolt under Madog ap Llywelyn, mainly against the actions of new royal administrators in north and west Wales. The uprising quickly spread to Glamorgan, where it was led by Morgan ap Maredudd, a local Welsh ruler dispossessed by Earl Gilbert in 1270, and attacks were directed against the de Clare estates. Morlais Castle was captured, and half the town of Caerphilly was burnt - although the castle itself held out. Eventually the rebels surrendered, not to de Clare but to the king himself.
 
Earl Gilbert died at the age of 52 in December 1295, and his estates were administered by his widow until her death in 1307. The young heir, another Gilbert, was killed at the battle of Bannockburn in 1314. His untimely death meant the extinction of the de Clare male line, and the Gloucester inheritance was divided among three sisters.
