text_A: Eleanor's marriage to Henry was reputed to be tumultuous and argumentative, although sufficiently cooperative to produce at least eight pregnancies. Henry was by no means faithful to his wife and had a reputation for philandering. Henry fathered other children with Eleanor throughout the marriage, and his affairs were largely inconsequential. Eleanor appears to have taken a forgiving attitude towards these affairs, and she remained devoted to her growing family. Geoffrey of York, for example, was a recent child of Henry and Eleanor, and raised by both parents as a royal heir at Westminster.
text_B: If DNA testing was widely available at this time, would there be several children with "royal blood" who nonetheless lived as commoners and had different last names?
NO.
