Question: Who is the spouse of the person who suggested that the ratio of silver to gold should be fixed?

full_context: Document 1: William Thomas Hamilton: William Thomas Hamilton (September 8, 1820October 26, 1888), a member of the United States Democratic Party, was the 38th Governor of Maryland in the United States from 1880 to 1884. He also served in the United States Senate, representing the State of Maryland, from 1868–1874, and in the House of Representatives, representing the second district (1849–1853) and fourth district (1853–1855) of Maryland.
Document 2: History of the United States dollar: The history of the United States Dollar refers to more than 240 years since the Continental Congress of the United States authorized the issuance of Continental Currency in 1775. On April 2, 1792, the United States Congress created the United States dollar as the country's standard unit of money. The term dollar had already been in common usage since the colonial period when it referred to eight - real coin (Spanish dollar) used by the Spanish throughout New Spain.
Document 3: United States dollar: The dollar was first based on the value and look of the Spanish dollar, used widely in Spanish America from the 16th to the 19th centuries. The first dollar coins issued by the United States Mint (founded 1792) were similar in size and composition to the Spanish dollar, minted in Mexico and Peru. The Spanish, U.S. silver dollars, and later, Mexican silver pesos circulated side by side in the United States, and the Spanish dollar and Mexican peso remained legal tender until the Coinage Act of 1857. The coinage of various English colonies also circulated. The lion dollar was popular in the Dutch New Netherland Colony (New York), but the lion dollar also circulated throughout the English colonies during the 17th century and early 18th century. Examples circulating in the colonies were usually worn so that the design was not fully distinguishable, thus they were sometimes referred to as "dog dollars".
Document 4: Silver standard: In 1704, following Queen Anne's proclamation, the British West Indies became one of the first regions to adopt a gold standard in conjunction with the Spanish gold doubloon coin. In 1717, the master of the Royal Mint, Sir Isaac Newton, introduced a new mint ratio as between silver and gold, and this had the effect of putting Britain onto a de facto gold standard. Following the Napoleonic Wars, the United Kingdom introduced the gold sovereign coin and formally adopted a gold standard in 1821. At the same time, revolutions in Latin America interrupted the supply of silver dollars (pieces of eight) that were being produced at the mints in Potosi, Mexico, and Lima, Peru. The British gold standard initially extended to some of the British colonies, including the Australasian and Southern African colonies, but not to its North American colonies, British India, or to Southeast Asia. The Province of Canada adopted a gold standard in 1853, as did Newfoundland in 1865. In 1873, Imperial Germany changed over to the gold standard in conjunction with the new gold mark coin. The United States changed over to gold de facto in the same year, and over the next 35 years, all other nations changed to gold, leaving only China and the British colonies of Hong Kong and Weihaiwei on the silver standard. The silver standard finally came to an end when it was abandoned by China and Hong Kong in 1935.
Document 5: United States dollar: The U.S. dollar was created by the Constitution and defined by the Coinage Act of 1792. It specified a "dollar" to be based in the Spanish milled dollar and of 371 grains and 4 sixteenths part of a grain of pure or 416 grains (27.0 g) of standard silver and an "eagle" to be 247 and 4 eighths of a grain or 270 grains (17 g) of gold (again depending on purity). The choice of the value 371 grains arose from Alexander Hamilton's decision to base the new American unit on the average weight of a selection of worn Spanish dollars. Hamilton got the treasury to weigh a sample of Spanish dollars and the average weight came out to be 371 grains. A new Spanish dollar was usually about 377 grains in weight, and so the new U.S. dollar was at a slight discount in relation to the Spanish dollar.
Document 6: United States dollar: The Gold Standard Act of 1900 abandoned the bimetallic standard and defined the dollar as 23.22 grains (1.505 g) of gold, equivalent to setting the price of 1 troy ounce of gold at $20.67. Silver coins continued to be issued for circulation until 1964, when all silver was removed from dimes and quarters, and the half dollar was reduced to 40% silver. Silver half dollars were last issued for circulation in 1970. Gold coins were confiscated by Executive Order 6102 issued in 1933 by Franklin Roosevelt. The gold standard was changed to 13.71 grains (0.888 g), equivalent to setting the price of 1 troy ounce of gold at $35. This standard persisted until 1968.
Document 7: William Thompson (Upper Canada): He was born in New Brunswick in 1786, the son of a United Empire Loyalist, and came to Grantham Township with his family in 1809. He served as captain in the local militia during the War of 1812 and fought at the Battle of Queenston Heights. He was taking prisoner by the Americans while on a scouting expedition. When he returned, his father had died and their property damaged; he settled in Toronto Township. He built a sawmill with his brother in 1817. During the Upper Canada Rebellion, he served as colonel in the York militia and became lieutenant colonel in 1846. In 1824, he was elected to the 9th Parliament of Upper Canada for York and Simcoe. He was a conservative member, with close ties to members of the so-called "Family Compact". After several attempts at reelection, he retired to local politics. In 1844, he became a member of the township council and was reeve in 1851.
Document 8: William S. Hamilton: William Stephen Hamilton (August 4, 1797 – October 9, 1850), a son of Alexander Hamilton and Elizabeth Schuyler Hamilton, was an American politician and miner who lived much of his life in the U.S. state of Illinois and territorial Wisconsin. Hamilton was born in New York, where he attended the United States Military Academy before he resigned and moved to Illinois in 1817. In Illinois he lived in Springfield and Peoria and eventually migrated to the lead-mining region of southern Wisconsin and established Hamilton's Diggings at present-day Wiota. Hamilton served in various political offices and as a commander in two Midwest Indian Wars. In 1849 he moved to California on the heels of the California Gold Rush. He died in Sacramento, most likely of cholera, in October 1850.
Document 9: William H. Stevenson: William Stevenson was born in Kenosha, Wisconsin and his family moved to La Crosse, Wisconsin when he was young. Stevenson graduated from the La Crosse Normal School (now the University of Wisconsin–La Crosse) and taught in area high schools. He went to law school in Madison and was admitted to the bar. Stevenson was District Attorney for Richland County, Wisconsin from 1924 to 1926. He moved to La Crosse and was District Attorney for La Crosse County from 1935 until 1941. In 1940 he was elected to the 77th United States Congress representing Wisconsin's 3rd congressional district. He was reelected to the following three congresses as well serving from January 3, 1941 till January 3, 1949. Stevenson died in La Crosse and was buried in Onalaska, Wisconsin.
Document 10: William Henry Harrison: William Henry Harrison Sr. (February 9, 1773 -- April 4, 1841) was an American military officer, a principal contributor in the War of 1812, and the ninth president of the United States (1841). He was the last president born before the American Revolution, and died of pneumonia just 31 days into his term, thereby serving the shortest tenure in United States presidential history. He was the first president to die in office, and his death sparked a brief constitutional crisis. Its resolution left unsettled Constitutional questions as to the presidential line of succession until the passage of the Twenty - fifth Amendment to the United States Constitution in 1967. Harrison was a son of Founding Father Benjamin Harrison V and the paternal grandfather of Benjamin Harrison, the 23rd United States President (1889 -- 1893).
Document 11: Dime (United States coin): The Coinage Act of 1792, passed on April 2, 1792, authorized the mintage of a "disme", one-tenth the silver weight and value of a dollar. The composition of the disme was set at 89.24% silver and 10.76% copper. In 1792, a limited number of dismes were minted but never circulated. Some of these were struck in copper, indicating that the 1792 dismes were in fact pattern coins. The first dimes minted for circulation did not appear until 1796, due to a lack of demand for the coin and production problems at the United States Mint.
Document 12: William Henry Harrison Tomb State Memorial: The William Henry Harrison Tomb State Memorial is the final resting place of William Henry Harrison, ninth President of the United States; his wife Anna Harrison; and his son John Scott Harrison, Representative and father of the twenty-third President, Benjamin Harrison. It is located on Brower Road approximately one-half mile west of U.S. Route 50 in North Bend, Ohio.
Document 13: Gold standard: In the 1780s, Thomas Jefferson, Robert Morris and Alexander Hamilton recommended to Congress the value of a decimal system. This system would also apply to monies in the United States. The question was what type of standard: gold, silver or both. The United States adopted a silver standard based on the Spanish milled dollar in 1785.
Document 14: United States dollar: From 1792, when the Mint Act was passed, the dollar was defined as 371.25 grains (24.056 g) of silver. Many historians[who?] erroneously assume gold was standardized at a fixed rate in parity with silver; however, there is no evidence of Congress making this law. This has to do with Alexander Hamilton's suggestion to Congress of a fixed 15:1 ratio of silver to gold, respectively. The gold coins that were minted however, were not given any denomination whatsoever and traded for a market value relative to the Congressional standard of the silver dollar. 1834 saw a shift in the gold standard to 23.2 grains (1.50 g), followed by a slight adjustment to 23.22 grains (1.505 g) in 1837 (16:1 ratio).[citation needed]
Document 15: Henry Gratiot: The second eldest son of Illinois pioneer Charles Gratiot, Sr. and Victoire Chouteau, Henry Gratiot was born in St. Louis, Spanish Upper Louisiana Territory, in the present-day State of Missouri.
