hehee... i can for the US/Europe/Japan
everywhere else alot of information like that is classified ... for some odd reason.
Just need to search the international registry of residence - must be a legitimate member who doesn't want to use the information you gain for commercial or abusive purposes. Basically for finding lost friends, family members etc - break the agreement on it they black book your name.
Probably an interesting little fact that you could find out going there (different for each country so check your local info beurau) but the "Lettan" surname currently registered world wide there are 12
2 - Toronto, Canada
1 - Irvine, USA
2 - Hertfordshire, UK
4 - Greater London, UK
3 - Derby, UK
1 - Kiroshimka, Japan
probably spelt the Canadian and Japanese ones wrong
but is one of the smallest, i mean compare that to the 580,000 "Smiths" world wide (no i'm not gonna list them
)
i always found that service very interesting.
