Elizabeth Mallory

She was on her first marriage by 1461, so an earlier rather than a later birthdate is preferable.

ELIZABETH BRUYN (d. March 7, 1493/4) Elizabeth Bruyn, sometimes called Anne, was born between 1444 and 1450, the daughter of Sir Henry Bruyn/Bruen of South Ockendon, Essex (1420-November 30, 1461) and Elizabeth Darcy (d.c.1471). Her first husband was Thomas Tyrrell (d.1471), by whom she had two sons, William and Hugh. She then married Sir William Brandon (d. August 21, 1485), who died at Bosworth Field. They had at least three children, William (d. yng), Anne (d. by July 1540), and Charles (1484/5-1545) and some genealogies also list Robert, Richard, and Elizabeth. The latter was probably one of Brandon’s two illegitimate daughters. Elizabeth married third William Mallery or Mallory. [Unfortunately, we do not know which William Mallory - there were several. He is sometimes given the title "Esq.", but never knight. Hikaru Kitabayashi, a dedicated Mallory researcher, thinks he may have been connected to the Papworth Mallorys.]

By Elizabeth Bruyn, William Brandon had two sons and a daughter :

   William Brandon.

   Charles Brandon, 1st Duke of Suffolk.
