I want to restrict this specifically to ordinary speech, as I am well aware of then-contemporary lingering uses of "thou" and "thee" in fossilized legal and religious language, as well as in certain types of literature.
In certain areas of the UK (Lancashire and Yorkshire in my experience), older people still use thee and thou.
Eg when my grandma used to babysit me she’d say “it’s just me and thee tonight”. This was prob 20 years ago now but I’ve heard it since then, but that’s the most personal example I can come up with
