This is a studio portrait of Jessie Catherine Thorburn, nee McKenzie, (1824-1916) with her daughter Mary Susan Thorburn (1850-1927). Jessie McKenzie, aged 15, arrived in Australia from Scotland with her parents and five siblings in 1839. She married a Scottish-born farmer named Robert Thorburn in 1846. They began married life at Numbaa , on the Berry estate in the Shoalhaven district of New South Wales, part of an extended Scottish Presbyterian community. Jessie was widowed in 1869 and in 1886 relocated with her unmarried daughters from the family farm at Barr Hill, near Jaspers Brush, to live in a newly built house called Meroogal in Nowra, financed by her eldest son Robert Taylor Thorburn. Mary Susan was her eldest daughter. She married schoolmaster Roderick McGregor in 1868. They lived with their family of eight children at Torrisdale at the foot of Mt Cambewarra, not far from Nowra. This ambrotype is a pair to a portrait of Robert Taylor Thorburn and his sister Belle, the second of Jessie’s daughters. Both pictures are housed in ornate moulded thermoplastic cases manufactured by John Smith of Birmingham.
