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.

2101623Martha de Shelving's parents are 4203246John de Shelving and 4203247Benedicta Bourne, as explained below. Her brother James was born circa 1322,1 so we can use that as a rough estimate of when 2101623Martha herself was born.

Problem: Resolved
Who are 2101623Martha's parents?

An inquisition post mortem for the estate of 4203246John de Shelvyngge, the writ for which was issued on 6 February 1329/30, mentions his wife 4203247Benedicta and 8 year-old son James.1 (Elsewhere, 4203247Benedicta's maiden name is shown to be Bourne.2)

Intriguingly, a patent roll dated 27 September 1341 mentions 4203247Benedicta and James together alongside 2101622Thomas de Dene and his wife 2101623Martha.3

4203246John's inquisition post mortem also mentions a manor at Boughton Monchelsea, which 4203247Benedicta had brought into the marriage.1 We know that 2101623Martha's granddaughter 525405Benedicta would later own this manor.4

Based on the patent roll and the inheritance, 2101623Martha's parents certainly seem to be 4203246John de Shelving and 4203247Benedicta Bourne. As supporting evidence, we also see that 2101623Martha's descendants would claim Shelving arms in later heraldic visitations,5,6 and a pedigree among Edward Dering's manuscripts shows that the compiler describes 2101623Martha as the daughter of "Benedicti de Shelvinge" (i.e., 4203247Benedicta).7

As alluded above, 2101623Martha had married 2101622Thomas de Dene by 27 September 1341.3

2101622Thomas doesn't appear in later records, so it's plausible that he died fairly young, yet I have seen no evidence that 2101623Martha re-married. (In a mildly confusing sentence, Hasted seems to claim that 2101623Martha re-married to Sir John Gousall,8 but this claim is inconsistent with a patent roll which shows that John Gosehall and his wife Elizabeth sued 2101623Martha's mother 4203247Benedicta.9)
