it seems to me you want a hash of hashes of arrays.
so something akin to this?

my %name;
my $cur_name;
while(<YOUR_FILE>){
  chomp;
  my ($key,$value) = split(/:\s{2}/,$_);
  if ($key !~ /^$/){
    if ($key =~ /^Name/){
       $cur_name = $value
    }else{
       push @{$name{$cur_name}{$key}},$value;
    }
  }
}
