She bore to Sir Robert five sons, who all died without issue, and two daughters, Alice and Margery; the latter married to Nicholas Berners, of Aberden Hall, in Debden, and Codham Hall, in Wethersfield, whose daughter Catharine was wife of Sir William Fynderne; but this estate was the inheritance of Alice, the eldest daughter, married to John Helion, Esq. of Bumpsted Helion.

John Helion, Esq. was their son and heir, who, dying in 1450, left, by his wife Editha, daughter and co heiress of Thomas Rolfe, Esq. of Gosfield, Philippa, married to Sir Thomas Montgomery, Esq. of Faulkbourne Hall; and Isabel, the wife of Humphrey Tyrell, Esq. of Little Warley, to whom she bore an only daughter, named Anne, who, by marriage, conveyed this and other great estates to Sir Roger Wentworth, of Codham Hall, in Wethersfield.

John's father and mother were both heirs, and Morant calls him the "last heir male of this ancient family". His own co-heirs were his two daughters. Richardson lists some of his importance holdings as "Belchamp Otto, Belchamp Walter, Bumpstead-Helion, Gernon (in Wormingford), Ovington, and Parkhall, Essex etc." He also mentions that John left a PCC will proved 27 July 1450 (PCC 12 Rous).

Breton: Brito, or Le Breton. No less than nine of this name appear in Domesday Book: all of them probably Breton knights that had followed the fortunes of Alain-le-Roux or his kinsmen. Alured Brito held of the King a barony of twenty-two lordships in Devonshire: Gozelin another in Bucks, Gloucester, and Bedfordshire; Oger one in Leicester and Lincoln; Rainald one in Sussex; Tihel one in Essex and Norfolk; Waldeve one in Lincoln and Cheshire; and Maigno or Manno Brito one in Bucks and Leicestershire. Two others, Roger and William, were mesne-lords in Somerset and Huntingdon. It would seem an endless—not to say a hopeless—task to disentangle the genealogies of all these various adventurers from Brittany; the more so as many of them probably assumed the name of their manors. This was the case with Richard Brito's descendants in Nottinghamshire. Annesley, part of the great fee held by Ralph FitzHerbert at the time of Domesday, was held under him by "one Richard, who probably was father or ancestor of Ralph called Brito, who, together with his son Reginald de Anesleia, gave the church of Felley to the Priory of St. Cuthbert de Radford, near Worksop, in the year 1158."—Thoroton's Notts. From him descended Francis Annesley, first Viscount Valentia, temp. James I., and the Earls of Anglesey, Mountmorris, and Annesley. Maigno Brito, the Buckinghamshire baron, was the ancestor of the Wolvertons of Stoke-Hamond (one of his manors mentioned in Domesday), where they continued for a considerable time. —Lysons.

Banks enumerates several "persons of great eminence" bearing this name among his Barones Pretermissi. Amongst them are Ranulph Briton, of Northamptonshire, Chancellor to Henry III., as well as to his Queen, who died of apoplexy about 1247; John Briton, Bishop of Hereford, one of the King's Justices in the same reign; another John, seated in Norfolk, who affixed his name to Edward I.'s memorable letter to the Pope as Johannes le Briton, Dominus de Sporle; and William Breton, whose identity has never been satisfactorily established, who had a writ of military summons to attend the King at Newcastle in 1295.

Morant informs us that the surname of the "Tihell Brito" of Domesday was De Helion, and that he founded a flourishing and richly-endowed family in Essex, which gave the name to their seat of Bumsted-Helion. Their barony was, however, subjected by the Empress Maud to Alberic de Vere, Earl of Oxford. The last heir-male, John Helion, whose mother, a very great heiress, had brought the estates of the Swinburnes and Bottetourts, died 28 Hen. VI. He had himself acquired Gosfield Hall through his wife, Alice Rolf; and the whole accumulated inheritance centred on his second daughter, Isabella Tyrell; the eldest, who had married Sir Thomas Montgomery, of Falkborn Hall, being childless.
