I am looking for any information on David Christian Frederick BAHN who was born approx. 1824 in Kothen Anhalt Germany and died 1876 in Australia. David's marriage certificate lists parents as Philip BAHN and Wilhimine WITTIG. David came to Australia around 1853 and married Mary Ann SMITH (from Devon England) whose parents were William SMITH and Sarah PALFREY. David and Mary Ann had 4 sons John Frederick Otto born 1859, Albert Herrman born 1860, Charles Edward born 1862 and David Christopher born 1864. Someone has to know something or else have a connection as I am facing a brick wall and am desperate for any information. Please help! Thanks, Zandra.
