Janet Marion Snodgrass was born at
Doogalloook, a station on the
Goulburn River near
Yea, Victoria. She was the daughter of Charlotte Agnes (née Cotton) and
Peter Snodgrass. Her father, who died when she was 16, was an affluent landowner and a member of parliament. Her paternal grandfather was Colonel
Kenneth Snodgrass, a Scottish-born
British Army officer who became a colonial administrator in New South Wales, while her maternal grandfather – the owner of
Doogallook – was the naturalist
John Cotton. In 1873, aged 21, Janet married
William Clarke, 41-year-old widower for whom she had previously worked as a governess. She was stepmother to the four children from his first marriage, and bore an additional eight children herself (two of whom died young). In 1874, her husband inherited a substantial fortune from his father,
W. J. T. Clarke. He became the largest landowner in the country, and an exceedingly generous philanthropist, for which in 1882 he was raised to the
baronetage (the first Australian to be so honoured). ==Socialite==
