Question: Who was the dad of the composer of Symphony No. 41?

full_context: Document 1: Franz Xaver Wolfgang Mozart: Franz Xaver Wolfgang Mozart (26 July 1791 – 29 July 1844), also known as Wolfgang Amadeus Mozart, Jr., was the youngest child of six born to Wolfgang Amadeus Mozart and his wife Constanze. He was the younger of his parents' two surviving children. He was a composer, pianist, conductor, and teacher from the late classical period whose musical style was of an early Romanticism, heavily influenced by his father's mature style.
Document 2: Violin Sonata No. 35 (Mozart): It is the last of Mozart's substantial violin sonatas, with the only remaining work he wrote for this combination, the sonata in F, K. 547 of 1788 being more of a sonatina. It is also considered by several authors, including Alfred Einstein, to be part of his last series of three great violin sonatas which starts with the Regina Strinasacchi sonata in B-flat K. 454 from 1784 (his annus mirabilis, the year also of the six great piano concertos 14 – 19 and the quintet for piano and winds) and continuing with the E-flat violin sonata from December 1785. The first movement is a movement in sonata form in 6/8 time, with more evenly divided contributions between the two instruments than in the earliest of his sonatas, an exposition divided between its two tonal groups (A and E major), and a compact but unwasteful development section.
Document 3: Biographies of Mozart: Wolfgang Amadeus Mozart died after a short illness on 5 December 1791, aged 35. His reputation as a composer, already strong during his lifetime, rose rapidly in the years after his death, and he became (as he has remained to this day) one of the most celebrated of all composers.
Document 4: Symphony No. 30 (Mozart): Wolfgang Amadeus Mozart wrote Symphony No. 30 in D major, K. 202/186b in Salzburg, completing it on May 5, 1774.
Document 5: Symphony No. 41 (Mozart): Wolfgang Amadeus Mozart completed his Symphony No. 41 in C major, K. 551, on 10 August 1788. The longest and last symphony that he composed, it is regarded by many critics as among the greatest symphonies in classical music.
Document 6: Symphony, K. 45b (Mozart): This work was only known to Ludwig Ritter von Köchel as an incipit in the catalogue of Breitkopf & Härtel, and thus it was placed in the Anhang as K. Anh. 214. Alfred Einstein then discovered a set of parts in the Berlin State Library with the title ""Synfonia Ex Bb...Del Sigr. cavaliere Amadeo Wolfgango Mozart Maestro di concerto di S.A. á Salisburgo"". Wolfgang became the Concertmaster to the Archbishop of Salzburg in November 1769, and was given the title "cavaliere" in July 1770, but as this is a later copy, this information cannot be used for dating purposes. Einstein believed the symphony to date from early 1768 on stylistic grounds; Neal Zaslaw and Gerhard Allroggen believe even earlier dates to also be possible, and Zaslaw dated the symphony cautiously to Salzburg in 1767. Einstein also believed that the symphonies in the catalogue of Breitkopf & Härtel were sent by Leopold Mozart to be published.
Document 7: Luigi Gatti: Luigi Gatti (October 7, 1740 – March 1, 1817) was a classical composer. He was born in Lazise in 1740, the son of an organist, Francesco della Gatta. He was ordained a priest in Mantua. In the 1780s he became Hofkapellmeister in Salzburg and Leopold Mozart showed his irritation at not receiving it himself. Between 1801 and 1804 Gatti helped Mozart's sister, Nannerl to locate unknown pieces by Mozart. He died in Salzburg in 1817.
Document 8: Mozart's birthplace: Mozart's birthplace (German: ' or ') was the birthplace of Wolfgang Amadeus Mozart at No. 9 Getreidegasse in Salzburg, Austria. The Mozart family resided on the third floor from 1747 to 1773. Mozart himself was born here on 27 January 1756. He was the seventh child of Leopold Mozart, who was a musician of the Salzburg Royal Chamber.
Document 9: Symphony, K. 97 (Mozart): The Alte Mozart-Ausgabe (published 1879–1882) gives the numbering sequence 1–41 for the 41 numbered symphonies.

The symphony K. 97 is given the number 47 in this numbering scheme.
Document 10: Symphony, K. 96 (Mozart): The Alte Mozart-Ausgabe (published 1879–1882) gives the numbering sequence 1–41 for the 41 numbered symphonies. The unnumbered symphonies (some, including K. 96, published in supplements to the Alte-Mozart Ausgabe until 1910) are sometimes given numbers in the range 42 to 56, even though they were written earlier than Mozart's Symphony No. 41 (written in 1788). The symphony K. 96 is given the number 46 in this numbering scheme.
Document 11: Symphony, K. 95 (Mozart): The Alte Mozart-Ausgabe (published 1879–1882) gives the numbering sequence 1–41 for the 41 numbered symphonies. The unnumbered symphonies (some, including K. 95, published in supplements to the Alte-Mozart Ausgabe until 1910) are sometimes given numbers in the range 42 to 56, even though they were written earlier than Mozart's Symphony No. 41 (written in 1788).

Document 12: Wolfgang Amadeus Mozart: Wolfgang Amadeus Mozart (/ ˈwʊlfɡæŋ æməˈdeɪəs ˈmoʊtsɑːrt / MOHT - sart; German: (ˈvɔlfɡaŋ amaˈdeːʊs ˈmoːtsaʁt); 27 January 1756 -- 5 December 1791), baptised as Johannes Chrysostomus Wolfgangus Theophilus Mozart, was a prolific and influential composer of the Classical era.
Document 13: Symphony: At the beginning of the 19th century, Beethoven elevated the symphony from an everyday genre produced in large quantities to a supreme form in which composers strove to reach the highest potential of music in just a few works. Beethoven began with two works directly emulating his models Mozart and Haydn, then seven more symphonies, starting with the Third Symphony (``Eroica '') that expanded the scope and ambition of the genre. His Symphony No. 5 is perhaps the most famous symphony ever written; its transition from the emotionally stormy C minor opening movement to a triumphant major - key finale provided a model adopted by later symphonists such as Brahms and Mahler. His Symphony No. 6 is a programmatic work, featuring instrumental imitations of bird calls and a storm; and, unconventionally, a fifth movement (symphonies usually had at most four movements). His Symphony No. 9 includes parts for vocal soloists and choir in the last movement, making it a choral symphony.
Document 14: Wolfgang Amadeus Mozart: Wolfgang Amadeus Mozart was born on 27January 1756 to Leopold Mozart (1719–1787) and Anna Maria, née Pertl (1720–1778), at 9 Getreidegasse in Salzburg. This was the capital of the Archbishopric of Salzburg, an ecclesiastic principality in what is now Austria, then part of the Holy Roman Empire. He was the youngest of seven children, five of whom died in infancy. His elder sister was Maria Anna Mozart (1751–1829), nicknamed "Nannerl". Mozart was baptised the day after his birth, at St. Rupert's Cathedral in Salzburg. The baptismal record gives his name in Latinized form, as "Joannes Chrysostomus Wolfgangus Theophilus Mozart". He generally called himself "Wolfgang Amadè Mozart" as an adult, but his name had many variants.
Document 15: String Quartet No. 18 (Mozart): Wolfgang Amadeus Mozart's String Quartet No. 18 in A major, K. 464, the fifth of the Quartets dedicated to Haydn, was completed in 1785. Mozart's autograph catalogue states as the date of composition ""1785. / the 10th January"". It is in four movements:
