My GGGF, Carl Frederick Edward OSTEN was born in Tütz Prussia in 1848. He emigrated to New Zealand in 1872 from Hamburg. It is likely that had he had any brothers or sisters they most probably emigrated to U.S.A during the same period.
I would really like to contact any OSTENs in the states to share info. There are very few of us here in NZ!

Thank you
Karl Osten
