The marriage you may be talking about.John de la Pole on Feb 7 1450 as a
small child Married Lady Margaret Beaufort,The Pope gave dispensation to marrie
Aug 18 1450,but that marriage was annulled inFeb 1453.Lady Margaret was 7 yrs
old.As unlikely as it sounds marriages like this were condoned at the time as long
as both families agreed.So there are no children recorded.As far as Grace de la
Pole,i would need Dates for her.Could be the product of a descendant.
