James Egan Wall

Hello! I'm hoping someone on here might be able to help me. I'm researching my great great great grandfather, James Egan Wall. Based on current information I believe he was born in Loughrea around the year 1817. He may or may not have a brother whose initials are 'J.  H.' He trained as a pharmacist (I believe this was in Dublin and strongly suspect that there might be proof for his doing this in the October 19th, 1839 edition of the Freeman's Journal, although I still need to confirm this) and came out to Australia, arriving at some point around 1843 (according to his newspaper obituary in Australia). How he came out to Australia remains a great mystery as well, as no records have yet been confirmed for that either!

James Egan Wall has been one of the big family enigmas for my family for years, although we're finally getting somewhere with details of his life in Australia. However, his early life remains tantalisingly out of reach, with just the merest glimpse of the bare bones. If anyone has any information that might help fill in some gaps, it would be amazing. And on the off chance there is anyone over there who has the opposite problem and would like the Australian part of his life story that we've managed to puzzle out, I'd be more than happy to oblige. Thanks!
