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. Throughout the marriage, Henry's mistresses gave birth to children that he had fathered. Eleanor appears to have taken an ambivalent attitude towards these affairs. Geoffrey of York, for example, was an illegitimate son of Henry, but acknowledged by Henry as his child and raised at Westminster in the care of the queen.
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?
YES.
