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.

The inquisition post mortem that I've cited is in fact the only record that mentions 16812991Beatrice at all. It states that 16812991Beatrice died at Easter three years ago, but the record isn't dated. However, it's filed with—and very likely was completed around the same time as—two other inquisitions done in 1274.
