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.

A charter dated 12 June 1190 names several of 134503844Robert de Throwley's family members: his father 269007688Hamund, grandfather 538015376Hemfred, and wife Mabel.1

In the charter, 134503844Robert confirms his father's earlier grant of a church to the Abbey of Saint Bertin in France.1

134503844Robert's mother was probably 269007688Hamund's wife Matilda/Mabel, who is mentioned in a different charter written sometime between 1162 and 1165;2 there isn't enough evidence to be certain, however.
