From the same on-line dictionary source from which Helen took her recent definition of "barmecide" -- and a fun one it is;¹ thank you, helen -- come the following challenge:

Yethhounds n.: A pack of phantom hounds pursuing a lady. From old English folklore. Yeth comes from heath. Also called wishhounds. Wisely is it said that the English have a word for everything. How this particular one first came into existence is a mystery to the author, even allowing for the penchat of the English for specialist hunting dogs. There appears to be no equivalent term for a pack of phantom hounds pursuing a gentleman.

Can our fine minds find the missing term?

------------------------------------------------------

¹ Note: that particular dictionary-source is great fun, but should be taken with a grain of salt, for it is not scrupulously accurate.
See e.g. the recent post on xanthodontous; so too, that source's definition for barmecide is well beyond that of the more-recognized dictionaries.

Edit: "yethhounds" ... I'd bet there are very few words with a double-h.

Dear AR: The best I could do was find a site about a Welch myth:"The Hounds of Hell". Don't chase men.

Hopefully you mean Welsh, as in, from Wales and not welch which round my way means to default on a promise.

From Jane Austen's Emma:

enjoying the youthful simplicity which could speak with so much
exultation of Mrs. Martin's having "two parlours, two very good parlours,
indeed; one of them quite as large as Mrs. Goddard's drawing-room;
and of her having an upper maid who had lived five-and-twenty years
with her; and of their having eight cows, two of them Alderneys,
and one a little Welch cow, a very pretty little Welch cow indeed;

So, at least in Jane's day, Welch was a legitimate spelling for the word meaning from Wales.
