William Markwick

William Markwick was the son of James Markwick of Catsfield and Mary Eversfield, who were married in Eastbourne on 10 June 1735.{{cite book | url=https://books.google.com/books?id=zs2YIGYcFYMC&pg=PA196 | title=A Genealogical and Heraldic History of the Extinct and Dormant Baronetcies of England, Ireland, and Scotland | publisher=Burke's Peerage; reprinted by Genealogical Publishing | author=Burke, John | orig-year=1841| year=2002 | page=194 (as shown in book)| isbn=9780806307398 }}

He was nominally admitted to the Inner Temple to study law in May 1758, and equally nominally educated at Peterhouse, Cambridge in June 1758. However he neither practised as a lawyer nor took a Cambridge degree, choosing instead to live the life of an English country gentleman.{{cite journal | author=Slatter, Enid | title= William Markwick FLS a forgotten naturalist |url=http://www.linnean.org/Resources/LinneanSociety/Documents/Publications/The-Linnaen/Lin%20Vol%2020_%20no%201_%20Jan%202004.pdf| journal=The Linnean |date=January 2004 | volume=20 | issue=1 | pages=18–24}}

His estate covered 1600 acres of Sussex around Catsfield Place, also called Church House. He ordered short and delicate sheep's fescue grass seed to create an elegant greensward suitable for sheep, so that he could enjoy a view of sheep grazing outside his windows. Unfortunately, the story runs, the seed merchant supplied instead a much coarser grass, possibly giant fescue,{{efn|There are several species of fescue found in Britain, including Festuca arundinacea, Festuca heterophylla and Festuca gigantea, which can grow over a metre tall. Sheep's fescue grows no more than 60 cm tall.}} which grew so rank and tall that the sheep would not eat it, and it had to be controlled by scything.

On 30 June 1789, a few days after his fiftieth birthday, Markwick married Mary Date of Southampton (d. 1822){{cite web | url=http://www.connectedhistories.org/Search_results.aspx?pc=Catsfield&sr=bu&st=120 | title=St. James's Chronicle or the British Evening Post | publisher=ConnectedHistories | date=7 July 1789 | access-date=2013-04-10 | author=Anon}} and they had four children:

• Mary (1791-1810), who died unmarried;
• Sophia (1792-1843), who married Edward Bligh in August 1820, bringing him a dowry of £10,000;
• Charles (1794-1818), who bought a commission as an officer in the 10th Hussars and died unmarried;
• James, who became High Sheriff of Sussex in 1822, three earlier Eversfields having held the same office.

Markwick's aunt Olive Eversfield, who died in 1803, directed in her will that for her inheritance he must take the surname Eversfield, which he did,{{cite book | url=https://books.google.com/books?id=okhFAAAAYAAJ&pg=PA155 | title=County Genealogies. Pedigrees of the Families in the County of Sussex | publisher=Sherwood, Gilbert, and Piper | author=Berry, William | year=1830 | pages=155}} though he continued to use the name Markwick on (for instance) his scientific papers. He thus acquired Denne Park near Horsham, which caused long legal complications and consumed some years of his time. After his death, his widow and later his son James lived at Denne, selling the Catsfield estate.

Markwick was made a Fellow of the Linnean Society in 1792. His land along the south coast of Sussex and the Pevensey Levels, with the time available to a gentleman of leisure, enabled him to observe wildlife in detail around the year, in particular wetland birds and marine animals including fish. He noted Buffon's objections to the value of the beaks of birds such as the crossbill, calling it "a deformity", and of the black skimmer ("an awkward and defective instrument"). Markwick correctly pointed out that these were "admirably well formed" for their specific purposes and rebukes Buffon for "finding fault with the works of the Creator". The European Magazine, and London Review of 1792 reported On the Migration of certain Birds, and on other Matters relating to the feathered Tribes. by William Markwick, Esq., Associate [of the Linnean Society] had been published:{{cite journal | url=https://books.google.com/books?id=n1s3AAAAMAAJ&pg=PA199 | title=(Notice of) Transactions of the Linnean Society, Vol. 1. 4to. 18s.

Markwick was one of two Justices of the Peace living in Catsfield in 1791.{{cite web | url=http://www.sussex-opc.org/GBD1791/1791GBDBattle.htm | title=General British Directory 1791, Battle, Sussex | year=1791 | access-date=11 April 2013 | author=Anon}}

Markwick is known for his useful and pioneering work in phenology, the study of when annual events happen in nature.{{efn|Phenology has become increasingly important because of climate change.}}{{cite book | url=https://books.google.com/books?id=m7U94z35r3wC&pg=PT20 | title=Ecology: Plants, Animals, and the Environment | publisher=Facts on File | author=Allaby, Michael | year=2010 | pages=6 | isbn=978-0-8160-6100-6}} Some 500 of his detailed observations are documented in the second edition of Gilbert White's 1789 book The Natural History and Antiquities of Selborne. It was praised as "a work of great exactness, and the result of as much, and as patient observation as perhaps was ever brought to the subject. It is formed upon an attentive comparison of the seasons, from 1768 to 1793."{{cite book | url=https://books.google.com/books?id=uAAUAAAAQAAJ&pg=PA276 | title=The Works of Thomas Gray, Volume 3 | publisher=Pickering, William | year=1835 | pages=276 | editor=Mitford, John (The Rev.)}} The "Comparative View of White's and Markwick's Calendars" begins as follows:{{cite book | url=https://www.biodiversitylibrary.org/item/57615#page/481/mode/1up | title=A Comparative View of White's and Markwick's Calendars | year=1877 | access-date=11 April 2013 |author1=Markwick, William |author2=White, Gilbert | volume=1 }}
