Don't know where you live, but the Dutch government publishes spreadsheets with testdata. It contains names, middle names, addresses, domestic and foreign names, etc. No need to generate your own. I haven't had to use it yet and I didn't have a very good look, but I'd think it contains all sorts of exceptional cases which your system needs to handle. If it successfully processes that spreadsheet, it probably handles anything.
