Elizabeth Hunn Lander (born 1804 in Calstock) married Joseph Chynoweth, a brewer or maltster in 1822 in Calstock.
They had several children but Joseph died in 1838 leaving six children, one of whom, Eliza 1838, was born after his death.
Elizabeth then married her brother-in-law William Chynoweth in 1840. They had another four children.
In the 1860s the children went their separate ways.
Elizabeth Hunn Chynoweth 1828 and her husband went to Australia about 1866.
Father William son Joseph and dau Eliza went to Illinois, USA around 1867-8.
They are in 1880 census in Braidwood I think mother Elizabeth Hunn Lander went too, as I can't find a death in England for her.
James 1823, Henry 1834 and Jane 1850 all turned up in the parish of Loudoun, in Ayrshire, Scotland.
John 1831 and wife went to Canada, I think shortly after the birth of their son Joseph in Loudoun in 1867.
