Gioachino has a lot in common with the following three gentlemen below:
1.Johann Georg Nicolai (*24.06.1720, +24.12.1788) (Organist; Komponist; 1720 bis 1788) (No further content in his bio)
2. Emmanuel-Armand de Vignerot du Plessis-Richelieu, duc d'Aiguillon (31 July 1720 – 1 September 1788), was a French soldier and statesman, and a nephew Armand de Vignerot du Plessis, 3rd Duke of Richelieu (13 March 1696 – 8 August 1788). He served as the Secretary of State for Foreign Affairs under King Louis the Classical style.
3.Charles-Antoine Campion, italianized as Carlo Antonio Campioni (16 November 1720 – 12 April 1788[1]) was an Italian composer who was born in Lorraine. He was a prolific composer
.....and most propably with the following as well:
4.Frederick II (German: Landgraf Friedrich II von Hessen-Kassel) (14 August 1720 – 31 October 1785)
5.Carlo, Count Gozzi (13 December 1720 – 4 April 1806)[1] was a Venetian playwright and champion of Commedia dell'arte.

6.Friedrich Wilhelm Freiherr von Seydlitz[Note 1] (3 February 1721 – 8 November 1773[1]) was a Prussian officer, lieutenant general, and among the greatest of the Prussian cavalry generals.
7.Giovanni Battista Lorenzi (or Giambattista;[1] 1721–1807) was an Italian librettist. He was born in Puglia and died in Naples and was a friend of Giovanni Paisiello, with whom he collaborated on numerous operas.
8.Jean-Baptiste Berthier (1721–1804) was an officer (Lieutenant-Colonel) in the French Corps of Topographical Engineers during the reigns of Louis XV and Louis XVI.
