Eliza is said to be the daughter of Thomas Fordyce of Ayton.

In 1819, his life took another significant turn when he entered into matrimonial vows with Elizabeth Fordyce in the very heart of Edinburgh. Elizabeth, the daughter of Thomas Fordyce of Ayton and an Edinburgh Lawyer, brought her own notable lineage into their union.

She arrived at Hobart Town with his husband and family on the Britomart on 4 February 1822.

Eliza first lived with and later married James Thomson, a convict builder and architect. On her second marriage certificate the additional Christian name Fordyce may have been her maiden name. It was doubtless Ogilvie’s money which started Thomson on his prosperous career. In 1843-44 Thomson and his stepson Thomas Ogilvie were joint licensees of the British Hotel. Of Ogilvie’s daughters, Eliza Ann married William Henry Windsor (1821?-1889), later under-treasurer of Tasmania, and Mary Grant married James Goodall Francis (1819-1884), sometime premier of Victoria. Eliza died in Liverpool Street, Hobart, on 5 December 1852, aged 51.
