The leaflet states that Milson retained the lease until 1841, a John Jeffreys taking over the lease from that time. The North Sydney Council leaflet on Greencliffe states that Jeffreys Street and the wharf are named after him. It is likely that this is a mistake but there is no supporting evidence, indeed other Council records attribute the name to Arthur Jeffreys (refer Arthur Jeffreys below). There is no other record of a John Jeffreys in the early colony. The first record of any John Jeffreys arrived in Sydney on 10 April 1851 on the "Deucalion" from San Francisco. A John Jeffreys appeared before a magistrate in Paddington in the same year. Arthur (Frederick) Jeffreys (born in Surrey, England, in 1811) was a clergyman's son who decided to emigrate to Australia when aged in his late 20s. He arrived in Sydney on 20 February 1839, on the "Honduras". Prior to emigrating he was a commissioned lieutenant in the Royal Navy. Arthur Jeffreys married Sarah Campbell, the daughter of Robert Campbell, in 1841. In 1843, at the end of a severe five-year-long drought, Jeffreys purchased a property of , near Queanbeyan, NSW, which he named "Acton" after a town in Denbighshire, Wales. The name is perpetuated in the City of Canberra suburb of Acton, which forms part of the Australian Capital Territory. Robert Campbell was one of the considerable pastoralists, merchants and land-owners in the early colony of NSW with significant land holdings in Kirribilli, Duntroon on the Limestone Plains, and the Canterbury Estate near Sydney, among others. By way of marriage into the Campbells, Arthur Jeffreys, became a prominent land-owner in Kirribilli. There is no known record that Arthur and Sarah Jeffreys ever lived in the area. When Robert Campbell died in 1846, Arthur Jeffreys inherited a proportion of the estate in Kirribilli and also a large estate in what became the residential Sydney suburb of Canterbury. By this time Jeffreys was a wealthy man. A son was born on 30 Dec 1845, possibly John Jeffreys. In about 1850 Jeffreys built a "palatial colonial mansion", called Canterbury House in the modern day suburb of Canterbury. This was a large dwelling set at the end of a wide avenue of trees of sufficient importance and interest to have been painted by Conrad Martens. He subsequently became a member of the New South Wales Legislative Council (1851–54).
