comments=I would like to know if Joan Courtenay (b. about 1337), daughter of Hugh Courtenay and Margaret De Bohun, who married (about 1357) John Chiverton (b. about 1335) had any children. I have not been able to verify it, but I have found reference to a Miss Chiverton (said to be the daughter of John and Joan) who married Sir John Hallighwell. I am descended from the this Hallighwell line (Holwell in more recent times) and would like to know if indeed we are also descended from the Courtenay line.
