Jean-Antoine GASC was born in Verfeil, 30 kilometers east of Toulouse, in the French department "Haute-Garonne", on January 19, 1755.
In the late 1780's or early 1790's, i.e. shortly before the French occupation of the Netherlands, Jean-Antoine GASC moved to Amsterdam  where he married Maria Josephe "Josefina" CATEMBERG (or: KATTENBERG) on July 20, 1794. Jean-Antoine GASC died of the flue in Amsterdam on December 18th, 1800, at the age of 45.

On February 19, 1794 a son was born to Jean-Antoine GASC and Maria Josephe ("Josefina") Catemberg (or: Kattenberg). He was baptized the same day in the Roman Catholic "French Chapel" in Amsterdam and named Thomas Antoine after his godfather Thomas Antoine AVY.
In later documents Thomas Antoine was using the surnames GASCH or GASE. From 1822 onwards only the name GASE was used. Thomas Antoine GASE died in Amsterdam at the age of 90 on March 10th, 1884.
All 80 GASES that are living in the Netherlands, United Kingdom, Switzerland and Australia today are descendants of Jean-Antoine and Thomas Antoine GASE.
