James Robertson (1871-1868) came to Australia on the "Providence", arriving at Port Jackson on the 7th January, 1822. With him were his wife, Anna Maria Ripley, and six of their eight children, two more being born in the colony. James was granted 86 acres at Cremorne Point, which he later sold to James Milson.

James had been born in Renfrew, and trained as a clockmaker and silver smith. He worked in London before deciding to emigrate. On his arrival, he was appointed keeper of the Governments clocks and watches. 

James received a land grant on the north shore of the harbour, where he built  a house for his family. He also had  a grant at Baulkham Hills. His grant on the north shore became the suburb of Cremorne, while Robertson's Point still marks the position of his grant today.

James later received a land grant of 1,000 acres at Jerry's Plains, in the Hunter Valley, and the option to purchase another 1,000 acres.  The first grant became the property known as Plashett, named after the town in which his wife was born, and the second property was known as Strowan, a Robertson connection to Scotland.

James sold his Hunter Valley property in 1954, and moved to a farm on the subdision of Aberglasslyn, near Maitland. The original "Aberglasslyn House" still stands on this estate, which has now been sudivided for housing.

for some excellent pictures and information about the house. It seems that James Robertson did not live in this house.

James died in 1868 at Aberglasslyn and was buried near Maitland. Anna Maria died at the house of her daughter Lavalette and Dr Henry Graham.
