Edmund Deincourt's wife

Question

I was wondering if perhaps someone certified pre-1500 could look into the wife of Edmund Deincourt (Deincourt-2). 

I wrote the comment below on the profile regarding this:

Douglas Richardson states Joan de Clinton as being Edmund Deincourt's wife. pg. 674, Vol. II of Royal Ancestry "Edmund's widow, Joan Clinton." Also on pg. 259, Vol. II., Royal Ancestry, Ida Oddingsele and John de Clinton had a daughter "Joan, (wife of Edmund Deincourt)"

Then again I see it on pg. 119, Vol. IV., in Complete Peerage, "Joan his wife (late wife of Edmund s. of John Deincourt)" I've not seen where it is stated that Isabel Mohun is his wife.

I see a comment made in 2019 mentioning Douglas Richardson  and de Mohun-62 and de Ferrers-232 profiles. 

And I found this thread from 2002 on Google Groups. I'm guessing he must have changed his theory of Isabel Mohun being Edmund's wife. If I go by his books published in 2013 and what I found in Complete Peerage.

Looks like there were two Edmund Deincourts.

Complete Peerage

https://archive.org/details/completepeerageo04coka/page/118/mode/2up?view=theater

[Edmund Deincourt, Lord Deincourt ] "conveyed the said messuage, etc in Elmton, to himself for life: rem. to Hamon de Mascy and Joan his wife [late the wife of Edmund s. of John Deincourt], for her life"

and in the footnote on the same page

In 1326/7 Hamon de Mascy and Joan his wife  "quondam uxor Edmundi filii  Johannis Deyncourt' consanguinei Edmundi Deyncourt' avi predicti Edmundi defuncti"

consanguinei = kinsman

Edmund, Lord Deincourt's, heir was his grandson William.

Looks like Edmund, Lord Deincourt, had a son John who predeceased him. John had sons Edmund who married Joan Clinton but he died early, and William, who inherited.

Sometimes being like a dog with a bone really hurts my head, like in this instance.

It looks like Joan Clinton was married to Hamon de Mascy as a widow of Edmund Deincourt. Taken from Complete Peerage, Vol. IV., pg. 119 "...in Elmton, to himself for life: rem. to Hamon de Mascy and Joan, his wife [late the wife of Edmund s. of John Deincourt]."

Looking at the profile of Edmund Deincourt-2, this Edmund's parents are John Deincourt d. 1257 and Agnes Neville. If we look at pg. 673, Vol. II., Royal Ancestry - 11. William Fitzwilliam who was an adult before 1294, married Isabel Deincourt, daughter of Edmund Deincourt, knt. 1st Lord Deincourt of Blankney, Lincolnshire. On page 674, it states "In 1317 his father-in-law, Edmund Deincourt, enfeoffed him with property in Elmeton, Derbyshire in trust for Edmund for life, with remainders in succession to his grandson, Edmund's widow, Joan Clinton, and then to Edmund's great granddaughter, Isabel Deincourt. "

By looking at the dates alone, this leaves my to believe that this Edmund Deincourt is the same person as Edmund Deincourt-2. And that his wife was Joan Clinton and not Isabel Mohun. 

Does anyone know of any source to validate that Isabel Mohun is Edmund Deincourt's wife and not Joan Clinton?

Seems that Edmund Deincourt, Lord Deincourt, had a great granddaughter Isabel Deincourt, she presumably being a daughter of Edmund, son of John, son of Edmund.

The Mohun wife of Edmund Deincourt, Lord Deincourt, is another interesting conundrum.

Yes! I did see that on pg. 674, Vol. II., R.A. and thank you for pointing that out.

The evidence for Isabel Mohun is apparently:

A History of Dunster and of the Families of Mohun & Luttrell. By Sir H.C. Maxwell Lyte. Part 1, 1909, p 34 [Cited St George's extracts from the Mohun Chronicle] https://archive.org/details/historyofdunster01lyte/page/34/mode/2up

The Mohun Chronicle is now published.

Good job. Thank you!
