The Castells had been established in Warwickshire for several generations, although their property (primarily a manor in Withybrook) was not extensive. George was perhaps the son of the George Castell who in the 1340s had laid claim to land in Echills.
The date of Castell’s death is not known, and he may have died before March 1396 when his bailiff obtained a royal pardon of outlawry for failure to answer his master’s suit for the theft of some barley several years earlier. He was possibly the father of Robert Castell of Alspath, although there is no evidence that the latter ever held Withybrook, which in 1407 was sold by Thomas Compworth and his wife Elizabeth (the latter probably being a Castell and possibly George’s daughter).
