hello Caroline - Christian Gade is also my ancestor. I have discovered that he came out on the ship 'caesar and helene' from hamburg in 1857.he settled initially near the saddleworth area in s.a but then moved to the melrose/willochra plains area in s.a. His son Wilhelm is my great great grandfather. My grandfather was adopted by his uncle Ernst and aunt Martha after his mother Caroline died when he was about 3 years old. (Caroline was Ernst's sister and died at 24 yrs of age) Maybe you have been named after her ? have a lot of other details that I obtained from lutheran Archives in Adelaide, also a photo of the children of Ernst and Martha but seeing your message is almost 3 yrs old I will leave it at this and wait until i hopefully get a reply.
