Jane was baptised 30th October 1831, at Kingston, Cambridgeshire, England. She is the daughter of John Smith and Martha Wonner.  Since her next sibling was born by early March 1832, Jane was at least four or five months old when christened, perhaps older.
1841 Census: to add
On 8 July 1849, when Jane was 20, she married James Parish at Kingston, her father named as John Smith. 
Nine months later, they baptized twin girls: Louisa and Eliza.

The elder twin, Louisa, died shortly after the 1851 census. In November, James took his wife and child to Australia aboard the Caucasian. The ship arrived at Port Adelaide, South Australia, on 8 February 1852. They promptly added ten more children to their family over the next fifteen years: Annie, Smith, John, Martha, Mark, James, Sarah Jane, Mary Anne, Elizabeth, and William George. 
Some time after William was born in 1868, James and Jane moved to Victoria where they settled at Willenabrina, near Horsham.
In 1895, James passed away. Jane followed in 1901, aged 72. Her death was registered in Dimboola, her parents unknown to the informant. 
Jane is buried in Dimboola.

However, there are no known mtDNA test-takers in her direct maternal line.
It is likely that these autosomal DNA test-takers will share DNA with Jane:
