George Chapman 1835

[Carol Harris]

I am trying to trace the origins of George Chapman who was born (possibly at sea)circa 1835. He came to Australia in 1855.  He had a Swedish accent and was said to have a Swedish father and an English mother.
 
It is possible he was a descendant of William Chapman, brother of Fredric Henric Chapman.  Frederic had brothers, we know that at least one, William Chapman,was also a ship builder.
 
Can anyone help me with this query?
