Lady Margaret De Braose - Cracked dates running rampant

It gets worse. I have been trying to find out on what authority she is stated to be a de Braose/de Brewse. There is no primary documentation whatsoever, and the idea seems to have originated in an unsubstantiated guess in the Visitation of Norfolk, 1563.

The Braose/Brewse family was still highly prominent in the 14th century - the Wichingham/Wychingham family was not and never had been. It is therefore quite strange that no existing primary source makes reference to so illustrious a connection (no Wichingham impalement with Braose/Brewse, for instance).

Other (carefully sourced secondary) documents suggest that she may have been of the family Rising or Woodrising, who were about on the same level as the Wychinghams and from which the Wychinghams inherited property.
