Early Life
Thomas FitzWilliam was born before 1205, to
William FitzWilliam and
Ela de Warenne (the daughter of
Hamelin Plantagenet and
Countess Isabel de Warenne).
In
Baildon2 it is noted that:
[He] was of age in Michaelmas Term, 1225, when he confirmed to the Prior of Haverholme [near Sleaford, Lincolnshire] the land, etc. in Wardebergh [a lost village in Nottinghamshire] which Aubrey de Lisures, his grandmother, had given.
Thomas was the first known holder of Emley in 1253.
In
Extinct and Dormant Peerages3 it says:
...in 1241 he had summons to attend the King, with horses and arms; in 1266 he was with the barons at the battle of Chesterfield, and taken prisoner.
