Question: Which president of the St. George Social Hall Company was father of an American businessman, author, and Republican Party politician and grandfather of the 2012 Republican presidential nominee?
Context: George Scott Romney (born June 7, 1941) is an American Republican politician and lawyer in the state of Michigan.  He formerly sat on the Michigan State University Board of Trustees.  A member of the Pratt-Romney family—a well-known political family in Michigan—he is the son of former Michigan Governor George W. Romney and brother of the former Massachusetts Governor and 2012 Republican presidential nominee Mitt Romney.  He goes by the name of "Scott" in order to distinguish himself from his father. Thomas Edmund Dewey (March 24, 1902 – March 16, 1971) was an American lawyer, prosecutor, and politician.  He served as the 47th Governor of New York from 1943 to 1954.  In 1944, he was the Republican Party's nominee for President.  He lost the 1944 election to President Franklin D. Roosevelt in the closest of Roosevelt's four presidential elections.  He was again the Republican presidential nominee in 1948, but lost to President Harry S. Truman in one of the greatest upsets in presidential election history.  Dewey played a large role in winning the Republican presidential nomination for Dwight D. Eisenhower in 1952, and helped Eisenhower win the presidential election that year.  He also played a large part in the choice of Richard M. Nixon as the Republican vice-presidential nominee in 1952 and 1956. Lenore LaFount Romney (born "Lenore Lafount" but adopted the variation "LaFount"; November 9, 1908 – July 7, 1998) was an American actress and political figure.  The wife of businessman and politician George W. Romney, she was First Lady of Michigan from 1963 to 1969.  She was the Republican Party nominee for the U.S. Senate in 1970 from Michigan.  Her youngest son, Mitt Romney, is a former Governor of Massachusetts and was the 2012 Republican presidential nominee. The 2012 Republican presidential primaries were the selection processes in which voters of the Republican Party elected state delegations to the Republican National Convention.  The national convention then selected its nominee to run for President of the United States in the 2012 presidential election.  There were 2,286 delegates chosen, and a candidate needed to accumulate 1,144 delegate votes at the convention to win the nomination.  The caucuses allocated delegates to the respective state delegations to the national convention, but the actual election of the delegates were, many times, at a later date.  Delegates were elected in different ways that vary from state to state.  They could be elected at local conventions, selected from slates submitted by the candidates, selected at committee meetings, or elected directly at the caucuses and primaries. Robert Joseph Dole (born July 22, 1923) is an American lawyer and politician who represented Kansas in Congress from 1961 to 1996 and served as the Republican Leader of the United States Senate from 1985 until 1996.  He was the Republican presidential nominee in the 1996 presidential election and the party's vice presidential nominee in the 1976 presidential election. George Wilcken Romney (July 8, 1907 – July 26, 1995) was an American businessman, author, and Republican Party politician.  He was chairman and president of American Motors Corporation from 1954 to 1962, the 43rd Governor of Michigan from 1963 to 1969, and the United States Secretary of Housing and Urban Development from 1969 to 1973.  He was the father of former Governor of Massachusetts and 2012 Republican presidential nominee Mitt Romney and the husband of former U.S. Senate candidate Lenore Romney. The 2012 presidential campaign of Gary Johnson, the 29th Governor of New Mexico, was announced on April 21, 2011.  He declared his candidacy for the 2012 Republican Party nomination for President of the United States.  On December 28, 2011, Johnson withdrew his candidacy for the Republican nomination, and declared his candidacy for the 2012 presidential nomination of the Libertarian Party.  The 2012 Libertarian National Convention was held during the first weekend of May 2012.  On May 5, 2012, after promoting his libertarian-oriented political positions to delegates, Johnson received the most votes at the convention and became the official 2012 Libertarian presidential nominee.  On November 6, 2012, Johnson received just under 1% of the popular vote in the general election, amounting to more than 1.2 million votes, more than double what the Barr/Root ticket received in 2008.  This was the most successful result for a third-party presidential candidacy since 2000, and the best in the Libertarian Party's history by vote number at the time.  (Johnson ran again in 2016 and received nearly four times his 2012 vote total.) Electoral history of Ron Paul, Republican U.S. Representative from Texas (1976-1977, 1979-1985, 1997-2013), 1988 Libertarian Party Presidential nominee and candidate for the 2008 and 2012 Republican presidential nomination.

He was the president of the St. George Social Hall Company and the St. George Dramatic Association, and also served as a chief of police, attorney-at-law, newspaper editor, and architect.  One of his sons, Gaskell Romney, was the father of George W. Romney and grandfather of Mitt Romney. The St. George Opera House, also known as the St. George Social Hall, is a historic building in St. George, Utah.  It was originally built by the St. George Gardeners' Club as a wine cellar.  As wine demand decreased, the building was expanded to host theatrical productions.  It operated in this capacity until sold to the Utah-Idaho Sugar Company in 1936.  It was restored to an opera house in 1988 and is again open to the public.
