I have a possible relative who married a Jurgen Haack in Queensland, Australia. My ancestors emigrated to Wisconsin in 1856, but I suspect that due to the Civil War some of the family may have moved to Australia instead. An Australian family website indicates that Jurgen Haack was a deckhand on a ship called the Wandrahm which arrived in Queensland around 1863. It was one of several ships that formed the nucleus of the Bethania Colony which consisted entirely of German emigrants, many from the area northeast of Berlin called the Uckermark. The colonists described themselves as Wendish, meaning they were Germans with Slavic roots. The daughter of a passenger whose maiden name was Lubach, my surname, married Jurgen the Wandrahm deckhand. The ship apparently arrived in Australia with several cases of typhoid aboard so the passengers and crew were quarantined for about a year, a circumstance that may have contributed to their romance. Numerous subsequent Haacks married into the Bethania colony. If I recall correctly, Jurgen came from the Schleswig Holstein area which was part of Denmark until it was ceded to Germany in 1871.
