Claus left Hamburg with his family, in 1865, aboard the 'Susan Godeffroy' with his wife Anna Cathrina (nee Gripp) and six children; Heinrich (15), Fredrich (13), Magdalena (11), Ernestine (8), Maria (Mary) (6), Catharina (3) & Anna 1 year old. The trip was costly for the family and Claus lost his wife and no less than four children on the voyage (Fredrich and Magdalena may have also died at sea as there is no record of them in Australian records), testament to how dangerous such an undertaking was at the time.
It seems that the remaining family initially settled in Queensland for a time and likely would have been in contact with Johann and Catharina when they came out at the end of 1866. Claus moved to New South Wales around 1871 while his daughter Mary stayed on (possibly in the care of her relatives Johann and Catherine in Brisbane) until she turned 17 or 18 in 1876.
Claus lived at Palmers Island at Maclean, New South Wales where he died in 1881, while Mary married Olaf Heinrich Ebeling at Tomki, NSW where they had their first child, Minna Catherine (1879). The couple moved to Maclean around the time or just after Claus’s death and had another five children there, Anna Helena (1882), Henry Frederick (1884), May Florence (1888), Olaf William (1895) and Oscar A. (1899). Mary died in 1915, aged 56, at Myocum, Byron Shire, NSW.
