He was perhaps ''born'' in New York, on November 28, 1916. The very first P.G.Wodehouse story with Jeeves as a character was originally published in The Saturday Evening Post on that date.
Jeeves first name was Reginald(Reg),so the only tube station that fits may be Regents Park,as in:~
Reg
Gent's
Park.
I get the Reg and Gents but not the Park,so it's probably wrong!
However,
Here is an alphabetical list of all tube stations for you to peruse,and get annoyed over! LOL

Wodehouse also wrote lyrics for musical comedy and wrote a stage production of Leave it to Jeeves which never actually made the stage. In it Wodehouse says that Jeeves grew up in Brixton ( which is an Underground station ) .
I can't recall it being mentioned in the books . Mind you there are a shedload of books and it's a long time since I read any of them .
There is a book by C. Northcote Parkinson which is entitled A Gentlemans Personal Gentleman which gives background information about Jeeves and his birthplace may be mentioned in that .You could probably find a copy at a library..
