I am looking for information on my husbands Ahrens line. Peter Ahrens is supposed to have come from Germany and was an army officer there. He was married to Susan Williams and while living in Australia had several children. One of his children, Mary Ahrens was born 1 June 1858. She later married a Stanley Williams1 Sept 1877 in Tahiti and then settled in Oakland, where she died 15 Mar 1935. If anyone knows anything about this family, I would appreciate your help.
