This is a subject of endless debate on this mailing list! In fact, there are
people who have uncovered even more matches with different surnames than you
have. If you browse the archives for earlier in August, you can find the most
recent thread where this was reported. (Link to Browse off the URL below my
signature.) You probably have a relatively frequent haplotype.

A 25 marker test would undoubtedly eliminate some of them, but that's
probably not the best use of your money.
