From Nottingham chimney sweep to Echuca farmer

Lydia Watts, my second great grandmother, emigrated with her husband and two young children, aboard the "Africa". The Africa left Liverpool on 16 April 1858 and arrived in Melbourne, Victoria four months later on 14 August.
After the death of her father in 1845 Lydia's family had fallen on hard times. Lydia, aged 12,  looked after her  blind mother by working as a factory girl.
I had always thought her younger brother Lazarus had not survived the slum conditions in Nottingham but recently found him apprenticed to a chimney sweep in the 1851 England census and then aboard the Africa! Lazarus must have travelled to Ballarat with his sister's family for he found work as a sawyer at Mt Egerton before selecting land near Echuca. He became a successful farmer and died many years later.
It's heart warming stories such as this that make family history research worth while.
I wonder whether his sister's son-in-law, Samuel Baulch, only a few years younger than Lazarus ever stopped in Echuca on his way to and from his Cowabee farm?
