Andrew was born on 20 June 1835 at Hawick, Roxburghshire, Scotland, to John Tennant and his wife Jessie née Aitken. Soon after they migrated to South Australia with an assisted passage, arriving in the Duchess of Northumberland on 17 December 1839. A newspaper obituary had him arriving two days later with John Colton on the Duchess of Sutherland. Andrew was educated at E. W. Wickes' school in North Adelaide. John began "pastoral pursuits", initially at Dry Creek on the Adelaide Plains, and then at Chain of Ponds in the Adelaide Hills, Lyndoch Valley in the Gumeracha district, and Burra. John became the first person to successfully move stock overland from Adelaide, via Port Augusta to Port Lincoln at the southern tip of Eyre Peninsula. He purchased Tallala station, from Port Lincoln, from a Mr. White of White Park, and raised cattle and sheep there for many years. In 1853, Andrew commenced his own "pastoral pursuits", taking cattle west from Port Lincoln and settling for seven years on an abandoned site near Elliston, before owning several stations on southern Eyre Peninsula at Mount Wedge, Coffin Bay, and Streaky Bay. On 28 August 1862 he married Rachael Christina Ferguson in Adelaide.
Pastoralist
In 1866 he leased "Baroota" near Port Germein, and subsequently bought and sold a number of properties in the mid-north, north-east and far-north of South Australia, resulting in him owning a number of large stations of over in area. Although initially interested in cattle, he also developed an interest in sheep, and owned land further south near Riverton, and a number of stations in New Zealand. In 1880 his eldest son John moved to New Zealand where they took up 25,000 acres of pastoral land. Andrew also owned a number of properties in the city of Adelaide. Tennant and James Moseley in 1904 acquired and re-established the Yardea Station in 1904 after it had been abandoned a few years earlier.
Tennant died of diabetes and senile dementia in his home, Essenside,, on 19 July 1913, and was buried in the Brighton cemetery. He was survived by his wife, three daughters and three of his four sons.
Essenside
Essenside was located on the northern corner of Moseley and College Streets, Glenelg, a beachside western suburb of Adelaide.
1868-1876
Edward M. Bagot acquired the land in 1868 and erected an eight-roomed house on the site designed by Rowland Rees in 1873.
1877-1921
Andrew Tennant acquired the property in 1877 and made significant extensions to the original building.
Essenside Mansions
Mrs A Tennant died on Friday 13 May 1921. Essenside was put up for auction on Tuesday 20 December 1921. The house was purchased by Mr. A. A. Heaslip who divided it into nine flats and named the building "Essenside Mansions". The building was sold again in 1926, and again in 1930, but by now had become a "magnificent block of 10 self-contained flats". In the 1930s and 1940s, to spend one's summer holidays at Essenside Mansions was worthy of mention in the Advertiser's Social column. In July 1937 an announcement appeared in The Advertiser for "a bridge party for the St Peter's Glenelg Lacrosse Club" to be held at Essenside.
Andrew Tennant married Rachael Christina Ferguson on 28 August 1862, lived at Tallala Station near Port Lincoln, "Essenside", Glenelg. Their children were:
