From John-Ashdown-Hill, whose Private Life of Edward IV is published a month today:
“Can anyone find ANY CONTEMPORARY EVIDENCE to show that Edmund, Earl of Richmond, Jasper, Earl of Pembroke, or Henry VII ever used the name TUDOR?
That surname definitely was used by Owen.
For example, in 1459 Henry VI gave a commission to ‘Owin Tuder’ (CPR, 1452-1461, p. 494).
But although the indexes of the published versions of the CPR, CCR, &c, list Edmund, Jasper and Henry under that surname, I haven’t yet found one single entry which actually employs it.
SO IF YOU CAN FIND ANY EVIDENCE, PLEASE LET ME KNOW!”
