His epithet, and that of each previous and subsequent head of his family, was coined by John Smyth of Nibley (died 1641), steward of the Berkeley estates, the biographer of the family and author of "Lives of the Berkeleys".
[2] In the early 1340s he was one of the English knights who joined the forces of Alfonso XI of Castile in his crusade against the Moorish kingdom of Algeciras.
[3] He was subsequently retained by the Black Prince[3] and in 1355 joined his campaign in France.
[4] Wounded and captured at Poitiers,[5] it took him over three years to raise the money for his ransom.
Ill health apparently prevented his taking an active role in public life, following his return to England.
