I'm sure you will get good information from both boards Stoney.
It is admirable that you wish to search for yourself 
But why not just tell us a bit about the person you are looking for - name, dob, parents - and we will all help and see what we can find.

OK - here you go:
Archibald Meyers/Myers/Meyre (different spellings on different documents but all the same individual) - last record in the UK was 1851 census for Wetheral, Cumberland, aged 36, born Scotland. Wife Margaret (Bulman) with 9 children. I found a record of a further child born 1853. His wife remarried in 1857 and I was unable to trace any further details of what had happened to Archibald until a kind RC'er spotted this in a 1855 edition of the Carlisle Patriot:
"Carlisle Patriot July 28 1855
On the 15th December 1854 Mr Hugh Hart, at Castlemaine, Australia, late of Garden Street, London Road, aged 55 years: Same day and place, Archibald Myers, nephew of the above."
(I've previously tried to find out more - see:
http://www.rootschat.com/forum/index.php?topic=436028.msg2998727#msg2998727 but that was a good few years ago, a recent enquiry from one of my family members prompted me to try and pick up the search again)
Hugh Hart is mentioned as Archibald's Uncle - but until this point I've not heard any other connection with this person!? So I'm trying to figure out where he fits in.
It would seem they both went out to Australia lured by the gold rush. It must have been quite a desperate thing to up-sticks and leave a wife and 10 children behind - that's why I also wondered if he'd been sent as a convict. Another RC'er had searched passenger lists and at that time could only trace Hugh Hart, but today I see there's confirmation they both arrived in Victoria on the same ship (Thank you, Dundee!!)
I'm very grateful for the generosity and experience of others here and it would be good to resolve this once and for all - if that's at all possible! I'm glad that he might at last have been found, even if he died so far from home.
Many thanks to all of you!
