I am indebted to Jeff Pitt for part of the following information on Eliza.
Eliza was the youngest child of Thomas and Elizabeth Pitt. She was born on 1 November 1820 in Richmond and she was seven weeks old when her father Thomas died.
At some point Eliza went to live with her maternal grandmother Hannah Laycock in Sydney: she was registered living with her in the 1828 census. She inherited a house from Hannah when that lady died in 1831, when Eliza was only 11. She was 14 when her mother Elizabeth died.
On 14 February 1839 when Eliza was 18 she married her cousin Austin Forrest Wilshire, fourth child of James and Hester Wilshire. (He was named in honour of Hester’s sister’s first husband, Austin Forrest.) The house Eliza inherited from her grandmother was passed on to her husband on her marriage, as was the custom in those days.
The Wilshires lived first in Chippendale and then in Pitt Street, Redfern, where Austin Wilshire was working with his brother James in the Wilshire tannery business in George Street they had inherited from their father James. They had 13 children, of whom three died in infancy. Eliza died in childbirth at the age of 40 at their home in Glenmore Road, Paddington. Austin Wilshire died in 1889 at the age of 77.
