Michiel's son Jan (or Jehan) moved to France, first to Lille and then to Paris in 1585 to escape from the ongoing fighting between the Dutch and Spanish.
Jan Langhedul was given the title facteur d'orgues de Roy by King Henry III of France for the work he did in restoring the organ of Sainte-Chapelle in 1588.
[4] He restored the organs at Saint-Jean-en-Grève and Saint Benoit, where he replaced his father's spring-chest with a slider-chest to make repair easier.
It was rebuilt in 1859 by the Neuville de Rexpoëde brothers within Langhedul's original case, one of the oldest in Flanders.
[7] In 1613 he was in Brussels, the official organ builder of Albert VII, Archduke of Austria and his consort Isabella Clara Eugenia.
While in Brussels he worked on organs at Saint Gudula (1614), Begijnhof (1617), Hofkapel (1624–1625) and at the Notre Dame Cathedral in Saint-Omer.
[8] Matthijs worked with the English composer and organist John Bull in Antwerp between 1626 and 1627, where they built a ten-stop organ for the cathedral.
