She was 49 years older than her husband and 33 years younger than 2 of her sons?

Question

I have searched many other sites and cannot find any clarification of this situation.

Answer 1

All the dates are estimates, and clearly not checked for consistency. There is a 50 year span in the estimated birthdates of the children, also not very likely.

Comments

Yes.  The dates are stretched so that the first Hugh can be the man who steadied the elbow of the man who shot Harold, or something.  But he was actually Steward of Roger de Mowbray.  His DoB can be guessed at say 1100 and the other dates moved down accordingly.
