The Grey line.

THOMAS GREY, 1ST MARQUESS OF DORSET (1451-1501), was the elder son of
Sir John Grey, 7th Lord Ferrers of Groby (1432-1461), by his wife
Elizabeth Woodville, afterwards queen of Edward IV. He fought for Edward
at Tewkesbury, and became Lord Harington and Bonville by right of his
wife Cecilia, daughter of William Bonville, 6th Lord Harington (d.
1460); in 1475 he was created marquess of Dorset, and he was also a
knight of the Garter and a privy councillor. After the death of Edward
IV. Dorset and his brother Richard Grey were among the supporters of
their half-brother, the young king Edward V.; thus they incurred the
enmity of Richard duke of Gloucester, afterwards Richard III., and
Richard Grey having been arrested, was beheaded at Pontefract in June
1483, while his elder brother, the marquess, saved his life by flight.
Dorset was one of the leaders of the duke of Buckingham's insurrection,
and when this failed he joined Henry earl of Richmond in Brittany, but
he was left behind in Paris when the future king crossed over to England
in 1485. After Henry's victory at Bosworth the marquess returned to
England and his attainder was reversed, but he was suspected and
imprisoned when Lambert Simnel revolted; he had, however, been released
and pardoned, had marched into France and had helped to quell the
Cornish rising, when he died on the 20th of September 1501.

Dorset's sixth son, Lord Leonard Grey (c. 1490-1541), went to Ireland as
marshal of the English army in 1535, being created an Irish peer as
Viscount Grane in the same year, but he never assumed this title. In
1536 Grey was appointed lord deputy of Ireland in succession to Sir
William Skeffington; he was active in marching against the rebels and he
presided over the important parliament of 1536, but he was soon at
variance with the powerful family of the Butlers and with some of the
privy councillors.

He did not relax his energy in seeking to restore order, but he was
accused, probably with truth, of favouring the family of the Geraldines,
to whom he was related, and the quarrel with the Butlers became fiercer
than ever. Returning to England in 1540 he was thrown into prison and
was condemned to death for treason. He was beheaded on the 28th of July
1541 (see R. Bagwell, _Ireland under the Tudors_, vol. i., 1885).

THOMAS GREY, 2ND MARQUESS OF DORSET (1477-1530), the eldest son of the
1st marquess, fled to Brittany with his father in 1484
