Yorfrid's older daughter was heiress to the barony of Widnes, which included the Lancashire manors of Widnes, Appleton, Cronton and Rainhill. This barony was governed by her husband, usually noted to have been William FitzNigel 2nd Baron Halton (though some more recent accounts have her married to Nigel de Cotentin, 1st Baron Halton, and therefore the mother of William 2nd Baron). William 2nd Baron was father to a William 3rd Baron Halton and Widnes, who died with no issue. The barony was then passed through his sister Agnes to her husband Eustace fitzJohn (son of John FitzRichard), who became the 4th Baron of Halton & Widnes.
