Many thanks for all your suggestions. It will take me a while to work
my way through these as I have several open ends.


In a similar vein, the PERSONs names are
1) <firstname> <surname>
2) <initials> <surname> (more common)
3) <title> <initials>|<firstname> <surname>


Where I have firstname and or title I'd be quite keen to determine sex
as it would be interesting from a statistics point of view to
distinguish.

I am basically just interested in people from two countries, names
mainly English.
