Much of this has already been mentioned in earlier posts, but for what it’s worth here is what I have in part of my Norfolk page:

1e) Anne, 8th Countess
of Norfolk, 11th Baroness Mowbray and 12th Baroness
Segrave (Framlingham 10 Dec 1472-Greenwich 19 Nov 1481); m.Westminster 15 Jan
1478 Prince Richard, Duke of York, who was cr 1476 Earl of Nottingham, and 1477
Duke of Norfolk (b.Shrewsbury 17 Aug 1473, presumed murdered 1483); on her

her great-great-aunts

her son was cr Earl of Nottingham and Marquess of Berkeley, and Earl Marshal

1465); m.2nd Margaret Norreys, née Chedworth (d.1494); note:
according to a decision of the House of Lords in 1877, the abeyance in the
Baronies of Mowbray and Segrave was terminated ca 1484 in his favor, citing a
document wherein King Richard II called John “Duke of Norfolk, Lord Mowbray and
Segrave”, but John was not so known at the time; by the 1877 decision these
Baronies continued in the possession of the Howards until the death in 1777 of
the 9th Duke of Norfolk, when they again went into abeyance, though
none of these de jure holders actually claimed the title during this
period
