Regarding Fitz Hugh and Willoughby marriage

I would like to confirm whether Joan was the daughter of Henry Fitz
Hugh, 3d Lord Fitz Hugh, of Ravensworth in Richmondshire, Yorkshire, and
wife Elizabeth Grey. Magna Carta Ancestry, page 340, states she was one
of six daughters and married Robert Willoughby, 6th Lord Willoughby of
Eresby.

However, in apparent conflict, Magna Carta Ancestors, page 887, states
that Robert Willoughby, 6th Lord Willoughby of Eresby, married (1st)
before 21 Feb 1420/1 Elizabeth Montagu.

Leo Van de Pas' website states that Robert Willoughby, 6th Lord
Willoughby de Eresby, married (1) Lady Elizabeth Montagu before 21 Feb
1421 and that they had a daughter Joane, Baroness Willoughby de Eresby.

The Bradley web site states that Joan Fitz Hugh, born 1438, Ravensworth,
North Riding, Yorkshire, to Robert Willoughby and Elizabeth Montagu,
married Sir John Scrope, Lord Scrope on 22 Nov 1447.

I would be very appreciative of any information which will help to
clarify the parents and husband of this Joan(e).

Tim Powys-Lybbe...

Complete Peerage (hereinafter CP) says, Vol XII/2, pp.665-6, that Robt
Willoughby m. (1) bef 21 Feb 1420/1 Elizabeth de Montague and (2) bef 9
Jan 1448/9 Maud Stanhope.

There is no correction to this in CP Vol XIV.

However there are two items on Chris Phillips' CP Corrigenda site in the
proposed section:

but my guess is that the FitzHugh chart pedigree on Vol V, pp. 432/3 is
not right, though it may be the source for the entry in Magna Carta
Ancestry.

CP is usually far more reliable than other compendiums, by virtue of its
research methods and most of them use CP as a reference. Its cost
reflected the massive scholarship that went into it. And that is why
people think it worth maintaining, first by Vol XIV, the Corrigenda
Volume, and second by Chris Phillips' site for more recent discoveries.
