                    • TCP reports that this was one of the (longstanding) Irish Peerages that were recognised "by prescription" in 1489 King Henry VII "but of the date or mode of whose creation nothing certain is known."
                    • m. (before 1435) Anne Plunkett (dau of ?? Plunkett of Rathmore)
                      • ((A)) Robert St. Lawrence, 2nd Lord Howth, Lord Chancellor of Ireland (b c1435, d 1486)
                      • BP1870 identifies Robert as the 15th baron of Howth.
                      • m1. (before 1459) Alice White (dau of Nicholas White of Killester)

BP1870 appears certain that Joan was ancestress of the later Lords, referring within a note on the 19th baron to heritage from her.
