Olsen, John, to Australia ca 1850

[Bernard Casserly]

My greatgrandfather was called John Olsen or some similar name.He was born in Stockholm approx 1828 and had at least two sisters, Christina and Amanda. Amanda was killed in a skating accident.
William Olsen or similar was John's father's name. His mother's possible name was Anne Hamadi (it was unclear on John's marriage certificate.
Both John and William were mariners.
John went to Australia in about 1850 and was married there to Anne Mullins in 1855.
My name is Bernard Casserly and I now live in Anneberg, a part of the Kommun of Nässjö.
