I don't think it is a title, fanjo; I think the judge may have used that term as a possible reference to the legal principle in the US that people cannot be given titles of nobility, etc. For example, Americans can be knighted by the Queen, but they cannot call themselves Sir.
FWIW, names that are titles are used for firstnames in the US on a regular basis: Earl, Prince, Contessa, etc., and there are many surnames that are titles; King being the most obvious.
