Question: Who else was given the label in the quartet along with  Henry Drummond Wolff, John Gorst and a genuine Tory radical, who coined the term Tory Democracy ?
Context: One-nation conservatism (also known as one-nationism, or Tory democracy) is a form of British political conservatism that views society as organic and values paternalism and pragmatism.  The phrase "One-nation Tory" originated with Benjamin Disraeli (1804–1881), who served as the chief Conservative spokesman and became Prime Minister in February 1868.  He devised it to appeal to working-class men as a solution to worsening divisions in society through introducing factory and health acts, as well as greater protection for workers. The Fourth Party was a label given to a quartet of British MPs, Lord Randolph Churchill, Henry Drummond Wolff, John Gorst and Arthur Balfour, in the 1880–1885 parliament. James Henry Drummond (October 20, 1918 – December 12, 1950) is a former Canadian ice hockey defenceman.  He played in the NHL for the New York Rangers.  Drummond was born in Toronto, Ontario, Canada. Benjamin Disraeli, 1st Earl of Beaconsfield, (21 December 1804 – 19 April 1881) was a British statesman of the Conservative Party who twice served as Prime Minister of the United Kingdom, as well as a novelist.  He played a central role in the creation of the modern Conservative Party, defining its policies and its broad outreach.  Disraeli is remembered for his influential voice in world affairs, his political battles with the Liberal Party leader William Ewart Gladstone, and his one-nation conservatism or "Tory democracy".  He made the Conservatives the party most identified with the glory and power of the British Empire.  He is the only UK Prime Minister to have been of Jewish birth. Tory Boy was a character in a television sketch by comedian Harry Enfield which portrayed a young, male, Conservative MP.  The term has since been used as a caricature of young Conservative MPs.  Tory Boy was a repulsive thirteen-year-old, combining the characteristics of a snobbish, unpopular boy who went to school with Enfield, and those of an imagined younger version of William Hague.  Enfield also claimed to have mixed other recent Conservative politicians such as Michael Howard and Michael Portillo into the character, alleging that they were "Tory Boys who have never grown up."  The traits of "Tory Boy" have also been said to mirror those of a stereotypical member of the Federation of Conservative Students.  The Tory Boy image of a young Conservative MP has damaged some politicians.  William Hague struggled to shake off the stereotype and was often ridiculed for it during his leadership of the party.  Recently it has been argued that Conservative Future has managed to change the image of young Conservatives from that given by the FCS. Margaret MacDonald was born in 1815 in Port Glasgow, Scotland and died around 1840.  She lived with her two older brothers, James and George, both of whom ran a shipping business.  Beginning in 1826 and through 1829, a few preachers in Scotland emphasized that the world's problems could only be addressed through an outbreak of supernatural gifts from the Holy Spirit.  In response, Isabella and Mary Campbell of the parish of Rosneath manifested charismatic experiences such as speaking in tongues.  Around 1830, miraculous healings were reported through James Campbell, first of his sister Margaret MacDonald and then of Mary Campbell (through James's letter to Mary).  Shortly thereafter, James and George MacDonald manifested the speaking and interpretations of tongues, and soon others followed suit in prayer meetings.  These charismatic experiences garnered major national attention.  Many came to see and investigate these events.  Some, such as Edward Irving and Henry Drummond, regarded these events as genuine displays from the Holy Spirit.  Others, including John Nelson Darby and Benjamin Wills Newton, whom the Plymouth Brethren sent on their behalf to investigate, came to the conclusion that these displays were demonic. Stanley Drummond Wolff (4 February 1916 – 9 April 2004) was an English organist, choirmaster, composer, and music educator who was primarily active in North America.  His compositional output primarily consists of anthems for choir and works for solo organ.  In the 1980s he completed and published four volumes of hymns.  Many of his compositions have been published by Concordia Publishing House and MorningStar Music Publishers. Lord Randolph Henry Spencer-Churchill (13 February 184924 January 1895) was a British statesman.  Churchill was a genuine Tory radical, who coined the term Tory Democracy.  He inspired a generation of party managers, created the National Union of the Conservative Party, broke new ground in modern budgetary presentations, attracting admiration and criticism alike from across the political spectrum.  His most acerbic critics resided in his own party among his closest friends; but his disloyalty to Lord Salisbury was the beginning of the end of what should have been a glittering career.  His devoted son, Winston, who hardly knew his father in life, wrote a biography of him. The Drummond Professorship of Political Economy at All Souls College, Oxford has been held by a number of distinguished individuals, including three Nobel laureates.
