  1. not listed in Cracrofts Peerage
  2. TudorPlace lists 3 sons. "He had three sons, John his heir (who became 3d Earl of Salisbury), Thomas Montague, and Richard Montague, of whose issue there is no trace. This Richard lived ABT the year 1400. None of the English genealogies make any further mention of him except to state his name. It is claimed that there was also a fourth son, whose name was Simon Montague, and from 'in the nobility of England of this name claim descent'. Collins' Peerage, however, states that there is no evidence that this Simon ever lived, and is inclined to the belief that the nobility are descended from James Montague, a natural son of Thomas, 4th Earl of Salisbury. This James Montague had large possessions in County Kent, where he was a man of distinction, and is buried in the Church of Ludsdown in Kent."

Sir John de Montacute was born about 1360.
