try this.
function ToProper(S: String): String;
var
  Delimiter: Boolean;
  I, L: Integer;
begin
  Delimiter := True;
  L := Length(S);
  for I := 1 to L
  do
    if not (S[I] in ['a'..'z', 'A'..'Z'])
      then Delimiter := True
      else
      if Delimiter then
      begin
        if S[I] in ['a'..'z']
          then S[I] := Chr(Ord(S[I]) - 32);
        Delimiter := False;
      end
      else
        if S[I] in ['A'..'Z']
        then S[I] := Chr(Ord(S[I]) + 32);
  Result := S;
end;

Steve,

THis is pretty good. It even handle O'Doole correctly. If you add Mc and Mac like McDonald and MacAuthur I'll raise the points another 100 and award them to you.

Thanks,
Chad

Hi Chad,

What Steve is proposing is good. However, I have a comment. I have built case converters for professional products and in every case the robustness of the solution can only be solved by incorporating an exception dictionary. You will be amazed at how people's names don't follow the rules.

I think this is as far as you can go with this method, as Roger correctly points out.
// Capitalise Names
// 'maclintock' = 'MacLintock' :)
// 'macclesfield' = 'MacClesfield' :(
function ToProperName(S: String): String;
const
  CaseDiff = 32;
  Crlf = #13#10;
  Names = 'mc' + Crlf + 'mac';
var
  Delimiter: Boolean;
  I, J, K, L, M: Integer;
  NamesList: TStringList;
begin
  NamesList := TStringList.Create;
  try
    NamesList.Text := Names;
    K := NamesList.Count - 1;
    L := Length(S);
    Delimiter := True;
    for I := 1 to L do
    begin
      if S[I] in ['a'..'z', 'A'..'Z'] then
      begin
        if Delimiter then
        begin
          if S[I] in ['a'..'z']
            then S[I] := Chr(Ord(S[I]) - CaseDiff);
          Delimiter := False;
        end
        else
        begin
          if S[I] in ['A'..'Z']
            then S[I] := Chr(Ord(S[I]) + CaseDiff);
          for J := 0 to K do
          begin
            M := Length(NamesList.Strings[J]);
            if (I = M) then
              if ToLowerCase(NamesList.Strings[J])
                = ToLowerCase(Copy(S, I - (M - 1), M)) then
              begin
                Delimiter := True;
                Break;
              end;
          end;
        end;
      end
      else Delimiter := True;
    end;
  finally
    NamesList.Free;
  end;
  Result := S;
end;
