EdwardG,
You are right - I only had a minimal chance to test it. I think it works to your satisfacation. Sorry it took a while to get back to you - stupid thing called work ;-)
#!/usr/bin/perl
use strict;
use warnings;
my %name = map {chomp; $_ => undef} <DATA>;
my $num_names = 0;
for my $person ( keys %name ) {
my @names = split " " , $person;
$num_names = @names if @names > $num_names;
$_ = ucfirst lc $_ for @names;
$name{ $person } = \@names;
}
my $finished = 0;
my $index = 0;
while ( ! $finished ) {
my $update = 0;
for my $person ( keys %name ) {
next if ! $name{$person}[$index];
if ( $name{$person}[$index] =~ /(\w+)\w/ ) {
my $new_name = $1;
if ( ! grep { $new_name eq $_ }
map { $name{$_}[$index] }
grep { @{$name{$_}} == @{$name{$person}} } keys %name
) {
$update = 1;
$name{$person}[$index] = $new_name;
}
}
}
$index++ if ! $update;
$finished = 1 if $index > $num_names;
}
print "$_ => @{ $name{$_} }\n" for keys %name;
Cheers - L~R

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

Want more info? How to link
or How to display code and escape characters
are good places to start.
