Sometimes referred to as junior he was undoubtedly related to Henry Eccles the father of John Eccles. Henry was a composer and violinist whose performance for the Duke d'Aumont took him to Paris. In 1720 he composed 12 violin sonatas having borrowed numerous movements from the music of Valentini. Perhaps Henry was in service to the King of France by 1735 but this is not certain. Eccles composed a second set of violin sonatas in 1723 and they may well have been original. ~ Keith Johnson
