Thank you for your hard work, Sue, it's appreciated. Sorry about mentioning his daughter's name, but as she was named in the linked item I assumed it was OK. If I knew the name of the "wife", I could check for a marriage in Britain, but without that there are so many William Thomases that it would be impossible. Is it perhaps available via the daughter's birth registration - or was she not registered in Australia?
Regards,
Gareth
