Aged 30 years at the death of his father.
A manuscript narrating the foundation of Rievaulx
Abbey names Willielmum de Ros as son of Robertum de Roos
and his wife Isabellam hæredem D´Albany, adding
that he was buried in Kirkham monastery. He was summoned to parliament
in 1299, whereby he is held to have become Lord Ros of Helmsley.
William de Ros, 2nd Baron Ros, was summoned to parliament
as Baron Ros, of Hamelak, from 23 Jun 1295 to 6 Oct 1315. This nobleman
was one of the competitors for the crown of Scotland in 19 Edward
I , through his grandmother, Isabel, natural daughter of William
the Lion, King of Scotland. He was subsequently engaged in the wars
of Gascony and Scotland, and discovering the intention of his kinsman,
Robert de Ros, then Lord of Werke, to deliver up that castle to the
Scots, he lost no time in apprising the king, who thereupon despatched
him with 1600 men to defend that place, but the Scots attacking this
force upon its march cut it to pieces; when Edward himself advancing
from Newcastle-upon-Tyne soon obtained possession of the fort and
appointed Lord Ros its governor--allowing him, during his absence
in Gascony, to nominate his brother, Robert, lieutenant. Shortly thereafter,
he had a grant of this castle with its appurtenances forfeited by
the treason of his before-mentioned kinsman; and for several subsequent
years, his lordship was actively engaged in Scotland. In 1 Edward
II , he was constituted the king 's lieutenant, between Berwick
and the river Forth, and six years afterwards, he was appointed warden
of the west marches of Scotland. He married Maud, or Matilda, one
of the daughters and co-heirs of John de Vaux, who brought him the
manor of Feston and lands in Boston, co. Lincoln.
