Hi Cazay,
Ships Deserters - that's on Family History SA, am I right? - if so, he doesn't appear.
If he deserted ship he could also have done it in NSW or VIC seeing the Aconcaqua visited those States.
Hi aghadowey,
I did check your link but couldn't find anything positive to identify Edward Louis BRONSON b.c1851.
It seems likely that Edward has left USA for UK (maybe working on a ship) and then picked up work from UK to AUSTRALIA working on the Aconcaqua (as Cazay has posted).
We can definately say he has moved from USA to UK before Feb 1881 which is the date mentioned on the passenger list, UK to AUSTRALIA.
I'm not sure as to what other records I can check in the USA online.
Thanks again for your help,
Sashar
