Hi All. As far as I can piece it together after your help -
James Adams' application for Emigration to South Australia was documented on 22nd January 1836 for himself, his wife, and his daughter Mary Anne. His application was No. 29, embarkation No. 51. They embarked on the Cygnet, and departed Shadwell Basin on the 24th March 1836. Their previous address was recorded as 7 Princes Court, Whitcomb Street (London?). He was listed as a farm labourer.
Peter Baytup's application for emigration was documented on the 26th October, 1836, application No. 745, embarkation No. 442, on the Sarah & Elizabeth. His previous address was recorded as Wells Street, London. The Sarah and Elizabeth had already departed Hull on 27th September, 1836. He was listed as a seaman (whaler?).
Peter Baytup married Mary Ann Adams (date unknown) and they settled in Albert Town (Alberton).
James (John?) was born in 1841. He took up a selection near Balaklava, and became a blacksmith/ploughmaker, credited with inventing the "Stump Jumping False Comb" in 1869. He was my great grandfather. One of his sons became the mayor of Hindmarsh, and another produced the first Australian car capable of commercial production, unfortunately to be completely overshadowed by General Motors.
There was probably a second child, William, who died at age eleven.
There was probably a third child, Elizabeth, who never married.
It is believed that Mary Anne died in childbirth, either with Elizabeth or William.
After she died, Peter Baytup left the children as wards of the state and departed for the Californian goldfields on the Colonist, on the 12th January, 1850. It is possible that he died around 1852/3, because James is described as an orphan at around that time.
I can find no death records of Peter, Mary Anne, or Elizabeth. Nor birth records of Elizabeth or William. James died 16th December 1916.
Many thanks for all your help folks.
