Input: Elizabeth II
With Elizabeth's accession, it seemed probable that the royal house would bear her husband's name, becoming the House of Mountbatten, in line with the custom of a wife taking her husband's surname on marriage. The British Prime Minister, Winston Churchill, and Elizabeth's grandmother, Queen Mary, favoured the retention of the House of Windsor, and so on 9 April 1952 Elizabeth issued a declaration that Windsor would continue to be the name of the royal house. The Duke complained, "I am the only man in the country not allowed to give his name to his own children." In 1960, after the death of Queen Mary in 1953 and the resignation of Churchill in 1955, the surname Mountbatten-Windsor was adopted for Philip and Elizabeth's male-line descendants who do not carry royal titles.

What name did Elizabeth keep as her married name?
Output: House of Windsor

Input: Political party
In a nonpartisan system, no official political parties exist, sometimes reflecting legal restrictions on political parties. In nonpartisan elections, each candidate is eligible for office on his or her own merits. In nonpartisan legislatures, there are no typically formal party alignments within the legislature. The administration of George Washington and the first few sessions of the United States Congress were nonpartisan. Washington also warned against political parties during his Farewell Address. In the United States, the unicameral legislature of Nebraska is nonpartisan but is elected and votes on informal party lines. In Canada, the territorial legislatures of the Northwest Territories and Nunavut are nonpartisan. In New Zealand, Tokelau has a nonpartisan parliament. Many city and county governments[vague] are nonpartisan. Nonpartisan elections and modes of governance are common outside of state institutions. Unless there are legal prohibitions against political parties, factions within nonpartisan systems often evolve into political parties.
