Question: When was the wife of President of the United States Grover Cleveland born after who's name the village Folsom was named?
Context: Folsom is a village in St. Tammany Parish, Louisiana, United States.  The population was 716 at the 2010 census.  The town is named after the wife of Grover Cleveland, Frances Folsom.  It is part of the New Orleans–Metairie–Kenner Metropolitan Statistical Area. Grover Cleveland High School or Cleveland High School is the name of several public high schools in the United States, named—except as noted—for President Grover Cleveland: Frances Clara Folsom Cleveland Preston (July 21, 1864 – October 29, 1947) was married to the President of the United States Grover Cleveland and was the First Lady of the United States from 1886 to 1889 and again from 1893 to 1897.  Becoming First Lady at age 21, she remains the youngest wife of a sitting president. Following the American Civil War, the Baltimore and Ohio Railroad (B&O) created a vacation resort in the Appalachian Mountains of Western Maryland, in the small town of Deer Park, Maryland.  Constructed in 1873, the Deer Park Hotel was heavily promoted by the B&O railroad and became a favorite resort for the wealthy and prominent citizens of the Baltimore/Washington area.  Presidents Ulysses S. Grant, Benjamin Harrison, and Grover Cleveland were among its guests; William McKinley visited the establishment before he became president.  Even President Grover Cleveland spent his five-day honeymoon with his new wife, Frances Folsom Cleveland.  The Deer Park Spring, which had produced pure mountain water that was sold commercially, supplied the hotel, its swimming pool, and Turkish baths.  Deer Park's popularity declined after 1900 and the resort finally closed after the onset of the Depression in 1929.  The grand hotel itself was razed in 1944 due to a fire, although a few of the opulent cottages remain as reminders of the park's faded majesty. The second inauguration of Grover Cleveland as the 24th President of the United States took place on Saturday, March 4, 1893.  The inauguration marked the commencement of the second four-year term of Grover Cleveland as President and the only term of Adlai E. Stevenson I as Vice President.  Cleveland had previously been the 22nd president, and is the only president to serve two non-consecutive terms.  Chief Justice Melville W. Fuller administered the Oath of office.  It snowed during the inauguration. Adlai Ewing Stevenson I ( ; October 23, 1835 – June 14, 1914) served as the 23rd Vice President of the United States (1893–97).  Previously, he served as a Congressman from Illinois in the late 1870s and early 1880s.  After his subsequent appointment as Assistant Postmaster General of the United States during Grover Cleveland's first administration (1885–89), he fired many Republican postal workers and replaced them with Southern Democrats.  This earned him the enmity of the Republican-controlled Congress, but made him a favorite as Grover Cleveland's running mate in 1892, and he duly became Vice President of the United States. Folsom is a village in Union County, New Mexico, United States.  The population was 56 at the 2010 census, down from 75 in 2000.  The town was named after Frances Folsom, the fiancee of President Grover Cleveland. Esther Cleveland (September 9, 1893 – June 25, 1980) was the second child of Grover Cleveland, 22nd and 24th President of the United States, and his wife Frances Folsom Cleveland. The first inauguration of Grover Cleveland as the 22nd President of the United States was held on Wednesday, March 4, 1885, at the eastern portico of the United States Capitol in Washington, D.C..  The inauguration marked the commencement of the first four-year term of Grover Cleveland as President and the only term of Thomas A. Hendricks as Vice President.  Hendricks died days into this term, and the office remained vacant for the balance of it.  (Prior to ratification of the Twenty-fifth Amendment in 1967, no constitutional provision existed for filling an intra-term vacancy in the vice presidency.) President of the United States Grover Cleveland's first term (1885-1889) was most notable "for its record number of vetoes (414), more than double the number issued by all his predecessors combined."  During Cleveland's first term, controlling Congressional and wasteful spending was an important priority for him and his administration.  Cleveland's vetoes (and other moves, such as issuing "an executive order [which was later rescinded] directing the return of captured Confederate battle standards to their home states") angered the Grand Army of the Republic (GAR), a powerful organization advocating for Union veterans.  In his State of the Union Address in December 1887, President Cleveland called for lower tariffs and tariff reform, making it a major issue in the upcoming 1888 U.S. Presidential election.
