Question: Who was the mother of the woman who made the Star Spangled banner flag hoisted over a city that was designated a national park in 1925?

Context paragraphs:
Mary Young Pickersgill: Mary Pickersgill (born Mary Young; February 12, 1776 – October 4, 1857), was the maker of the Star Spangled Banner Flag hoisted over Fort McHenry during the Battle of Baltimore in the War of 1812.  The daughter of another noted flag maker, Rebecca Young, Pickersgill learned her craft from her mother, and, in 1813, was commissioned by Major George Armistead to make a flag for Baltimore's Fort McHenry that was so large that the British would have no difficulty seeing it from a great distance.  The flag was installed in August 1813, and, a year later, during the Battle of Baltimore, Francis Scott Key could see the flag while negotiating a prisoner exchange aboard a British vessel, and was inspired to pen the words that became the United States National Anthem.

Brown's Brewery: Brown's Brewery was a brewery located on East Lombard Street in Baltimore, Maryland.  In 1813, Mary Pickersgill sewed the famous Star Spangled Banner Flag in one of its malthouses.  At the time, the brewery was owned by Baltimore merchant George I. Brown who had bought it from Edward Johnson, the third Mayor of Baltimore.  George Brown sold the brewery to Eli Claggett in 1818, and until its final closure in 1879, it was known as Claggett's Brewery.  The site once occupied by the brewery was excavated in 1983 as the Baltimore Center for Urban Archeology's first project.

Amelia Fowler: Amelia Fowler, an embroidery teacher and well-known flag preserver, was the master needle worker who restored the original Star Spangled Banner in 1914.  By that time, the flag that inspired Francis Scott Key to write the United States national anthem was just "a frail piece of bunting."  But Fowler called upon her patented preservation techniques to save it from further deterioration.  She used dyed-to-match silk thread and employed ten assistants to reinforce the 1020 sqft relic.  They anchored it onto Irish linen with 1.7 million of Fowler's special honeycomb patterned, six-sided stitches.  It took eight weeks to finish the preservation process.  Upon completion, she claimed the restored flag would "defy the test of time," and charged the government $1,243.

Kathleen Key: Kathleen Key (April 1, 1903 – December 22, 1954) was an American actress who achieved a brief period of fame during the silent era.  She is best remembered for playing Tirzah in the 1925 film "Ben-Hur".  Key was the great-great granddaughter of Francis Scott Key, composer of "The Star Spangled Banner", and a distant cousin of author F. Scott Fitzgerald.

Whitney Houston discography: The discography of American singer Whitney Houston (1963–2012) consists of seven studio albums, six compilations, two soundtrack albums, five box sets, six extended plays, and fifty-seven singles.  In 1985, Houston released her self-titled debut album.  It spent fourteen weeks at number one on the "Billboard" 200 and was certified thirteen times platinum (Diamond) by the Recording Industry Association of America (RIAA), with global sales of 30 million copies.  The album produced four US top 5 singles, including three "Billboard" Hot 100 number-ones.  In 1987, Houston released her second album "Whitney".  The album debuted at number one on the "Billboard" 200 and was supported by four US number-one singles: "I Wanna Dance with Somebody (Who Loves Me)", "Didn't We Almost Have It All", "So Emotional", and "Where Do Broken Hearts Go", which established an unprecedented seven consecutive number one hits by a performer.  "Whitney" was certified Dimond by the RIAA and topped the charts in numerous countries, having sold in excess of 25 million copies worldwide.  Houston's third studio album, "I'm Your Baby Tonight" (1990), peaked at number three on the "Billboard" 200 chart and yielded two number-one singles; "I'm Your Baby Tonight" and "All the Man That I Need", selling 13 million units worldwide.  In February 1991, Houston released "The Star Spangled Banner" performance from Super Bowl XXV as a single, becoming the highest-charting rendition of the national anthem on the "Billboard" Hot 100 chart.

Frank Key Howard: Frank Key Howard (1826 - 1872) (also cited as Francis Key Howard) was the grandson of Francis Scott Key and Revolutionary War colonel John Eager Howard.  Howard was the editor of the "Daily Exchange", a Baltimore newspaper sympathetic to the Southern cause.  He was arrested without a warrant just after midnight on September 13, 1861 at his home by U.S. Major General Nathaniel Prentice Banks on the direct orders of General George B. McClellan enforcing the policy of President Abraham Lincoln.  (In his book he writes that he was told by the arresting officer that the order had come from Secretary of State William Seward.)  The basis for his arrest was for writing a critical editorial in his newspaper of Lincoln's suspension of the writ of habeas corpus, and criticizing the fact that the Lincoln administration had declared martial law in Baltimore and imprisoned without charge George William Brown, the mayor of Baltimore, sitting U.S. Congressman Henry May, all the police commissioners of Baltimore, and the entire city council.  Lincoln's suspension of habeas corpus in Maryland had already been declared unconstitutional by U.S. Supreme Court Chief Justice Roger Taney (Howard's great-uncle by marriage) in Ex parte Merryman, but Lincoln had ignored the federal court ruling.  Howard was initially confined to Fort McHenry, the same fort his grandfather Francis Scott Key saw withstand a British bombardment during the War of 1812, which inspired him to write The Star Spangled Banner, which would become the national anthem of the United States of America.  He was then transferred first to Fort Lafayette in Lower New York Bay off the coast of Brooklyn, then Fort Warren in Boston.

Whitney: The Greatest Hits: Whitney: The Greatest Hits is a compilation album by American singer Whitney Houston, released in May 2000.  The set consists of disc one with ballads and disc two with uptempo numbers and remixes.  Houston's performance of "The Star-Spangled Banner" at Super Bowl XXV, and 1988 Olympics tribute "One Moment in Time" are also included in the set.  The collection includes four new songs—"Could I Have This Kiss Forever", duet with Enrique Iglesias, "If I Told You That", duet with George Michael, "Same Script, Different Cast", duet with Deborah Cox and "Fine"—all of which were released as singles.  It also includes three other songs that had never appeared on a Houston album: "One Moment in Time", "The Star Spangled Banner", and "If You Say My Eyes Are Beautiful", a duet with Jermaine Jackson from his 1986 "Precious Moments" album.  Along with the album, an accompanying VHS and DVD was released featuring the music videos to Houston's greatest hits, as well as several hard-to-find live performances including her 1983 debut on "The Merv Griffin Show", and interviews.

Fort McHenry: Fort McHenry, in Baltimore, Maryland, is a historical American coastal pentagonal bastion fort best known for its role in the War of 1812, when it successfully defended Baltimore Harbor from an attack by the British navy from the Chesapeake Bay September 13–14, 1814.  It was first built in 1798 and was used continuously by U.S. armed forces through World War I and by the Coast Guard in World War II.  It was designated a national park in 1925, and in 1939 was redesignated a "National Monument and Historic Shrine".

Impartial Female Humane Society: The Impartial Female Humane Society was an early 19th-century benevolent organization established to assist distressed women in Baltimore, Maryland.  The society was formed in 1802 and incorporated in 1811.  Its most noted president was Mary Pickersgill, the seamstress who made the Star Spangled Banner Flag, who served from 1828 to 1851.  Under Pickersgill, the society opened an Aged Women's Home in 1851.  The home, which was supplemented with a men's home in 1864, became the focus of the society, and today the organization has evolved into the Pickersgill Retirement Community in Towson, Maryland.
