Not my direct line, but in the tree. Sarah TEE (1857-1945) was married to Thomas TREVITHICK (1857-1929), eldest son of 'my' Thomas TREVITHICK (1835-1913) who came to Australia from Cornwall. The Trevithick's lived in the gold mining town of Hill End / Tambaroora in NSW from at least 1870.
Sarah TEE was the daughter of William TEE (1814-1890), born in Brigstock, Northampton, England and transported to Australia as a convict on the 'Norfolk'. William TEE married Eliza SLACK in 1843 (NSW Cert V1843699 27C/1843) in the chapel at O'Connell Plains southeast of Bathurst. William carried out a timber business and the 1872 Greville Directory lists him as a sawyer at the Paling Yards, Tambaroora.
William and Eliza TEE had seven children apparently. The baptisms of two remain in the NSW BDM records, Mary Ann (born 1844 but baptised in 1848, of Grudgery NSW) and Elizabeth (born 1847 and possibly baptised at the same time). The third recorded was Sarah TEE, and the remaining four are accounted for in their mother's death certificate which states her issue to be two living children, and five deceased. In fact, when Sarah was born in 1857 her certificate indicates that her parents had already had six children, so she was the youngest.
Sarah TEE's mother is a little more mysterious. While the marriage certificate stated her name to be Eliza SLACK, on Sarah TEE's birth certificate in 1857 it is stated to be HOY. Eliza TEE died in 1871 aged 45 years of 'exposure and intemperence' in June 1871 on the road between Tambaroora and Hill End. Her death certificate listed her father as Samuel HOY, a soldier (mother not known). Her place of birth is given as Chesire, England (based on age at death she was born around 1826) and had been 34 years in New South Wales, so arrived from overseas aged 11.
Given this patchy information, it seems likely she was born to a soldier named Samuel HOY, and arrived in NSW with her father/family when he was posted there. But why the name Eliza SLACK at marriage (no other information is recorded except that she signed with her mark)? Records don't indicate the death of a wife and re-marriage to another Eliza (two wives would account for the variance). It is possible that she was a widower, however this is not stated on the certificate, and given that she was 17 it seems unlikely - there are no marriages that fit in the NSW BDM records either. Perhaps she was hiding, or the minister was simply confused.
Sarah married Thomas Trevithick (jnr) at Hill End in 1877 and they had 10 children (for some reason not all children were stated in the death certificate). They spent time in Hill End (gold mining) from their marriage till around 1884, then had children in Newtown (Sydney) 1885-1889, then back to Hill End from 1891 till at least 1903. In 1914 Thomas had moved to Sydney with Sarah and children. When he died in 1927, Sarah lived with her daughter Millie Edith.
