Jaki,
Thanks you very much for this info.
I received the other info in your personal email as well but was unable send my "thank you" with a direct reply as, apparently, I'm not authorised to send personal emails. This is my first day on RootsChat and I'll have to research how I can get authorised.
I'm also researching why Thomas didn't accompany Martha to Aus. I suspect it was because he had passed away; a Thomas Sample died in Alnwick, Northumberland in 1876 (Q3/10b/220). The feeble link to this is I believe Isabella was born in Alnwick (ENG/1856/Q4/10b/245). More research required.

Anyway, thanks again. And best wishes for the move.
Let me know when you're back on stream and if there's anything I can do to return the favour.
Best regards,
Mike
