Previously, I believed that the parents of 1050811Joan ___ were 2101622Thomas de Dene and 2101623Martha de Shelving. However, researcher Pete Andrews called my attention to 2101622Thomas' inquisitions post mortem, which I had overlooked. 2101622Thomas' two IPM's strongly suggest that he is not 1050811Joan's father (since the IPM explicitly notes 2101622Thomas' daughter Joan as deceased in early childhood, among other incongruences).

Nevertheless, because 1050811Joan certainly seems to be related to 2101622Thomas in some manner, and because my older work could prove useful for future research, I've isolated the profile pages that I'd written for 1050811Joan's formerly proposed ancestors into a separate section of my website, starting from the old version of Joan's page onward.

You can see a list of those ancestors or a family tree of them.

67251922Hamo de Gatton is the son of 134503844Robert de Throwley.1 His mother was probably 134503844Robert's wife Mabel,2 although there isn't enough evidence to be certain.

A charter of uncertain date shows that 67251922Hamo confirmed his grandfather's and father's earlier grant of a church to the Abbey of Saint Bertin in France. The charter shows that 67251922Hamo was married at the time, although his wife's name isn't provided; she is generally believed to have been 67251923Mabel de Gatton, as explained in her profile. The charter also included 67251922Hamo's seal, which was simply an etched chequy; its colors are not stated.1

67251923Mabel was a widow by June 1216,3,4 so 67251922Hamo must have died before then. A pedigree in Archaeologia Cantiana (Volume V, page 222 insert) presents some evidence that 67251922Hamo may have died during King John's failed military campaign in France in 1214.
