↑ Source: #S56 Sarah and Bryan Overend From a check of the musters and other indexes, it would appear that there was only one adult Sarah Anderson alive in Sydney during the period 1806 to 1825. Assuming this to be correct then Sarah had at least two children to Bryan Overend (variously speltBrian Overand/Overhead/Overhand) a convict who arrived on the Fortunein 1806 having been convicted at Lancaster and given transportation for 7 years(1). Sarah and Bryan were the parents of William born on 15 May 1808 and baptised on 7 August 1808 at Sydney (2), and Elizabethborn on 12 December 1809 and baptised on 3 August 1810 at Sydney (3).Sadly Elizabeth died within days of being baptised and was buried on 10 August 1810 (4), probably in the Old Sydney Burial Ground where theSydney Town Hall stands today. This then explains the third child as in 1814 Sarah would have been the mother of James aged about 11 years, Thomas aged about 9 years, and William aged 6 years. It seems that the relationship between Sarah and Bryan ended in 1809 or 1810 for Bryan married Catherine McNalty in 1810 (5). Then on 25 August 1810 Bryan Overend, master of the Lady Nelson, swore in Court that he was thefather of the illegitimate male child of Sarah Anderson (6). Bryan was appointed the master of the Lady Nelson on 27 May 1809. He was also the master of the Estramina in 1814, and may have been an officer of the brig Emu in 1815 (7). He then disappears from the records. His wife Catherine is listed in the NSW 1828 Census by herself. The following entries appear in the General Muster for 1822 (8) - James Anderson, Came Free, Seaman, Colonial Brig Elizabeth, Sydney Thomas Anderson, Born in Colony, Apprentice, Dock Yard, Sydney William Anderson, Born in Colony, Apprentice, R Uther, Sydney.

It may be possible to confirm family relationships with William by comparing test results with other carriers of his ancestors' Y-chromosome or mitochondrial DNA.
However, there are no known yDNA or mtDNA test-takers in his direct paternal or maternal line.
It is likely that these autosomal DNA test-takers will share DNA with William:
