getauft am 19. Dezember 1785 in Glenmuick, Schottland,
gestorben am 5. Juni 1872 in Lexton, Australien
 
Thomas Robertson (I) ein Sohn von James Robertson und Christian Robertson.
Er heiratete Anne Lachlan am 13. August 1815 und hatte mit ihr 5 Kinder, unter ihnen

(II).

The Robertsons in Scotland were subject to English law, which required births and marriages to be registered in the Church of England parish. This was unpopular (as well as costing money), and the parish registers are generally understood to be incomplete in the early years. The first time our family definitely appear is when James and Christian Robertson registered all their children's births at once, in about 1790. Thomas Robertson (I) was the third of four children born in Glenmuick to James Robertson and his wife Christian (née Robertson).

In 1839 the Robertsons emigrated to Australia. The elder Thomas took with him his children (his son Thomas was then fifteen) and the six children of his deceased sister Mary Gordon (the youngest was 11 years old). The young Robertsons all took advantage of government-assisted passages (bounty passages), which had only been introduced that year.
 
They sailed on the ship John Bull (705 tons; master, Captain Ormond), which left London on 22nd September 1839 and arrived at Melbourne on 21st January 1840 with 233 emigrants, 20 cabin passengers and merchandise.
 
The family remained in Victoria,  until the elder Thomas (I) died. Lexton, the place where Thomas Robertson died, is situated in the state of Victoria, on the Sunraysia Highway between Ballarat and Avoca, and was originally known as Burnbank when it was first settled in 1843.
