Those unsure of their origins?
I have a paperback book, assembled by a geneaology hobbyist in the family, which is about one of my ancestors who jumped the Portugese whaling ship he was bosun on in Sydney, disappeared for six months and then turned up again married.
Then there's the German roots. He was from Germany and a shearer, he and his wife lived in Greenacre when I was a child.
And the Welsh chap from Welshpool, who built a church there.
There are more, but I don't know of them.
