which "the" do you use before a surname

Question

I want to sign "The Jones" so which version of "the" is correct in front of a surname (last name)? Thanks.

Answer 1

Los Jones. The Spanish version of The Simpsons is Los Simpson (notice the family names goes singular - of course Jones in the singular, ie Mike Jones, contains an s, so it stays Los Jones.

Answer 2

I take it you mean "The Jones´s". I think you may have to sign off with something like

"La familia Jones".

Answer 3

You might want to put what you think the answer might be and let the users here help from there...
