To be honest I don't even know where to start, but one of my ancestors moved over to Melbourne from London (St Pancras). I would think in the late 1800's/early 1900's. His name was William Kirby. I've got an old letter from him (I think) but it provides no clues except he was in Melbourne and wished he wasn't?! Any ideas/thoughts on who I can ask for more info, would be v much appreciated.
