Recently, for the purposes of writing fiction, I had cause to check who was admitted to the Garter in 1387. (This is the sort of weird stuff I do all the time and helps explain why for me to write a book takes aeons.)
Anyway, the simple answer is Edward of York (later 2nd Duke of York) and Dame Katherine Swynford. Two very familiar names. And appointed for very obvious political purposes. To give favour to the father of one (Edmund of Langley) and the "close personal friend" of the other (John of Gaunt.) Note Katherine S was not languishing on her Lincolnshire muck-heap at this point, she was joining the most exclusive club going in the England of 1387.
But there was also someone called "Lady Gomeneys". Who the **** was she? I had literally no idea, but being me I had to find out. And with a fair bit of scrabbling around, I did. At least to a point.
Anne, Lady Gomeneys was the widow of someone called William de Graux, who had been accused of treasonable doings with the French, but had later been pardoned. So it looks very much as if Richard II felt that this woman had been hard-done by and wanted to make amends, not least by giving her the Garter! So this obscure widow got to sit with a carefully-chosen bunch of Plantagenets, high-born ladies, and widows and wives of distinguished English soldiers. She certainly had no discernable political heft, and this is at a point where Richard needed everyone he could bribe. It is notable, for example, that Henry Bolingbroke's wife did not get her Garter until the following year, when everything was very different politically.
On 13 November 1389 Anne Gomeneys was granted an annuity of 100 Marks, apparently as a further recognition of her innocence.
The surprising thing is that in 1409 Henry IV (who was not generous with these honours) granted Anne Gomeneys Garter robes again.
I would love to know more, but I suspect it would take a lot more searching than I can do from this desk.
