You have a normalized system I guess.  Welcome to the world of intense data
instead of simplistic Master with one or two child tables.

I have worked with a name table before because it greatly reduces index
stress in inserting and when you are searching for last name "Williams"
across 4 million rows it is much faster.  The text search to find 1 row out
of 4000 is instantaneous, and taking it's key value to the other table it
increases your search speed by a factor of 12 I found when I put this into
SQL Server 2005 system.  We had 4-6 million customers as I remember.
Customer support was real happy because they could find someone's record
without have to wait a while with them on the phone bitching about a
charge.
