Names can be a problem.... My travel buddy has a very common surname.. and from experience it would seem he shares a first name AND a DOB with a "person of interest" His passport has been held several times for further examination...

Best advice he got - the last time this happened - was to ensure his MIDDLE name was included on all travel documents/tickets etc... makes sense to me, that has got to reduce the chances of a "match" considerably...

As yyzvoyageur has suggested there will be a full match occasionally!

Never a nasty experience - the immigration folks were always pleasant...
