Giraldus Cambrensis mentions, that MacMurrough, having, in the year
1167, procured letters patent from Henry II., repaired to England, and
there induced Strongbow, Earl of Pembroke and Strighul, to engage to aid
him, on condition of receiving, in return, the hand of his _eldest_
daughter, Eva, and the heirship of his dominions.--_Girald. Camb._ p.
761. And further, that Strongbow did not arrive in Ireland until the eve
of St. Bartholomew's day, September, 1170; he was joined at Waterford by
Eva and her father, and the marriage took place a _few days after_, and
_during_ the sacking of that place.--Ibid. p. 773.
"Strongbow left, by his _second_ wife Eva, one daughter, named Isabella,
an infant. * * * Richard the First gave Isabella in marriage to William
de la Grace, who thus became Earl of Pembroke, and was created First
Earl Marshal of England," &c.--Fenton's _Hist. Pembrokeshire._
