Douglas Richardson, Royal Ancestry, Volume II, page 291, states in a paragraph on Henry de Erdington and his wife Joan de Wolvey, that "They had one son, Giles, Knt., and one daughter, ____ (wife of John de Grafton)."
Normally, It's a delight to find something in Richardson, but not here! First of all, Henry de Erdington seems to also have a daughter, Matilda, referenced by other credible sources. Secondly, I wish I knew Richardson's source for this so I could see what led him to be confident that there was a marriage without the daughter being named. But most importantly, there seem to be two John de Grafton's of the same age not terribly far from each other. Does anyone have a thought as to which one might be the spouse?
I was working on one of the John de Grafton's. This one took his name from a hamlet about 3 miles northwest of Shrewsbury, Shropshire. There were several generations of the family, documented in various Visitations, and while none of them had birth years, I gave them 30 years per generation, it all worked out and I had John born about 1300, and Henry de Erdington's daughter born 1310. Lovely.
There apparently was a more important family associated with Grafton Manor in Worcestershire which also went by the name de Grafton. And this family, too had a son John de Grafton, whose birth could be estimated as, say, 1295.
Neither son is listed in his respective sources with a named wife, or a wife at all, for that matter, though they both had descendants.
The link is to the John I was working on, but I've accumulated information on the other John (who does not have a Wikitree profile yet) under Research Notes on the same profile.
Your help in solving this puzzle -- or even shining more light on it -- would be most appreciated!
