I found your message a long time ago but never got around to answering it. In any event, You and I have a common ancester i.e. the father of Ulrich Huebbe, the notary public Johann Heinrich Huebbe.
Our family stayed in touch with our Australian relatives through many generations. We last received a visit in Hamburg after the 2nd world war. It was a young lady who came to Germany in order to find a husband and she ended up with a former U-Boat commander. We were pleasantly impressed by both of them. Unfortunately, I cannot remember their names. Maybe you can help me and tell me more about this nice couple.
