Rymill brothers
Henry Rymill (1 May 1836 – 21 February 1927) and Frank Rymill (27 November 1837 – 26 May 1915) were brothers prominent in business and public service in the 19th century South Australia. Henry "Harry" Rymill and Francis "Frank" Rymill were born in England, sons of Robert Rymill and Louisa (née Sheppard) Rymill of Shepperton, and migrated to South Australia, arriving at Port Adelaide in the Caucasian on 1 October 1855. Their company H & F Rymill was a prominent financial institution well into the 20th century. Their families included a number of prominent Adelaide citizens. Robert (1869–1906), Herbert (1870–1951) and Sidney (1873–1938) also traded as "Rymill Brothers

"Rymill Brothers" could also refer to the speedboat racing team of Arthur Graham Rymill (1868–1934) and Ernest Seymour Rymill (1876–1931) – see their notes below. It could also refer to the partnership of cricketer Jack Westall Rymill (1901–1976) and golfer William Seaton Rymill (1909–1987), actually cousins, who ran several sheep and cattle stations. Henry Rymill
Henry was working as a lawyer's clerk in London when persuaded by brother-in-law J. B. Graham of Prospect, South Australia to emigrate to the new colony. Despite numerous letters of introduction, he was unable to find congenial employment and finally at the home of Arthur John Baker (1814 – 4 July 1900), (Superintendent of the Fire Brigade and his future father-in-law) he was introduced to Captain Hughes (later Sir Walter Watson Hughes) who offered him employment as a gardener at Watervale. A. J. Baker's first wife was Margaretta Emily Potts née Lockett (1810–1890). Her step-sister Anne Potts (28 November 1812 – 14 August 1881) married Henry Ayers, and her step-brother was winemaker Frank Potts. Baker's second wife was Annie (ca.1841 – 30 April 1900). Their son Arthur (ca.1845 – 5 October 1856) was drowned in the Torrens. He soon attracted the attention of Henry Ayers, who was looking for a bookkeeper and cashier for the South Australian Mining Association in the Waterhouse Chambers ("Waterhouse Corner"). In 1862 he decided to go into business for himself and was so successful that around 1865 he took his brother Frank (by then secretary to the Commissioner of Crown Lands) into partnership. Aside from this business he became
Part-owner and director of Canowie Pastoral Company, a merino sheep stud
Director, Bank of Adelaide
Director, Adelaide Milling Company
Director, Victoria Insurance Company
Member, Central Board of Health
Director, Wyatt Benevolent Fund

H. & F. Rymill
Henry and Frank formed a partnership H. & F. Rymill as land agents and financiers around 1863, with offices at Pirie Chambers in Pirie Street. Much of their fortune was made in 1878 when they purchased from William King for £11,000 the lease on part of the land bounded by Pirie Street, Gawler Place, McHenry Street, part of town acres 169 and 170 purchased by George McHenry in 1837. By a quirk of fate and some shrewd dealing and legal wrangling, it was inherited by H & F Rymill in 1896. In 1929, in a move to minimise taxation, the property was divided between the two families: the family of Frank Rymill took Pirie Chambers and the block containing Selborne Chambers and the Selborne Hotel (erected by Josiah Symon, and later the Adelaide Hotel); and Henry Rymill's family the Exchange Buildings and King's Buildings. In 1879 they helped found a new Stock Exchange with G. Dutton Green as its head, on land known as "King's timber yard" in Pirie Street; they hired Edmund W. Wright to design the new building. The company prospered, becoming major investors and landholders in their own right. Their properties included Canowie Station (in which for decades they acted as agents for the absentee owners and eventually held a partial ownership) and Marra Station. References
