Umquhile

While reading "The Fair Maid of Perth" last night, I came across the following sentence:

"So please you, my liege," answered Sir Patrick, rising up, "this
woman, and these unhappy orphans, make plaint to your Highness
upon Sir John Ramorny of Ramorny, Knight, that by him, or by some
of his household, her umquhile husband, Oliver Proudfute, freeman
and burgess of Perth, was slain upon the streets of the city on
the eve of Shrove Tuesday or morning of Ash Wednesday."

I had never seen the word 'umquhile' before, so I decided to do a quick search. Just to prove once again the scope of the internet, here's a bit of a conversation I found discussing the word:

>>> >> >Hi all,
