↑ Birth year estimated as 25 years before estimated birth year of eldest son and heir, and also as 85 years before estimated birth year of grandson Sir Rowland Hill (son of Thomas), who was Mayor of London in 1549 and whose dates are given in Wikipedia as about 1495-1561.
Also, he lived during the reigns of Henry V and Henry VI, so he must have been born before 1422.
