Charles Augustus Vansittart Conybeare (1 June 1853 – 18 February 1919) was an English barrister and a radical Liberal politician who sat in the House of Commons from 1885 to 1895.
Conybeare was born at Kew, London, the son of John Conybeare, a wealthy barrister, and Katherine Vansittart. He was educated at Tonbridge School and Christ Church, Oxford where he won the Lothian Prize with a study on The Place of Iceland in the History of European Institutions. He was assistant master at Manchester Grammar School from 1877 to 1878 and was called to the bar at Gray's Inn in 1881. He married Florence Annie Strauss, the daughter of a Bohemian glass merchant, on 15 October 1896, at the Theistic Church in Piccadilly, London. She was an active member of the Women's Suffragette Movement. The couple began their married life in a spacious apartment at 3 Carlyle Gardens, Cheyne Walk, Chelsea, London. Charles Conybeare owned or leased Tregullow House, a country pile in Scorrier, Cornwall, that had been passed down through the Williams family, a well-known local family that had made their fortune in the mining of tin and copper.
Charles and Florence Conybeare were the co-beneficial owners of a property known as the Tregullow Offices, which Charles Conybeare bought in 1889 from the Williams family (mining moguls), and which he mortgaged in 1891 in order to raise some capital required for a marriage settlement. The financing of this marriage settlement, which effectively entitled Florence to half the value of the property in the event of desertion or divorce, was managed by Isaac Seligman, a wealthy and prominent German-born merchant banker based in London. The couple sold the property in 1902 to a Charles Rule Williams (no relation to the Williams mining mogul family), a retired mining engineer who renamed it Zimapan Villa
Conybeare owned Oakfield Park (the house) until the death of his wife Florence Annie in February 1916. Conybeare bought or leased the property which was situated within the grounds and estate of Oakfield Park.
