CHAT: "John Doe" equivalents sought

I've been asked on another mailing list to collect "dummy names" from
other cultures. In Anglo-America, the names "John Doe" and "Richard Roe"
(and female equivalents with "Jane") are used in the legal system and
elsewhere for people whose names are not known.  I have heard that
the name "Alain LaFlamme" is used similarly either in France or in
French Canada (my informant wasn't certain).  Are there other such names
elsewhere?  Details eagerly solicited.

ObConlang: In Lojban it would be "la broda", of course.

        Yes, I know the message date is bogus.  I can't help it.
