It is possible that this was the same Samuel Stevens who was working in Grub Street, London, between 1680-1703, and who was himself apprenticed to Edward Stanton. Thornton gained his Freedom in 1699 and by 1723 he was known to be working at 'ye Dial' in Basing Lane, suffering a burglary that year where a silver dial worth 18d, was stolen. He moved to the Royal Exchange around 1730. The last record of him in the Clockmakers Company is 1732, a date which is tentatively put forward as the year he died. There is an unusually high proportion of his extant work in Russia, suggesting that he had early business links with the court - two gold pocket watches from the Tsar's personal collection (one of which is repeating) are now in the State Hermitage Museum, together with a large musical organ clock with 12 tunes and gilt mirrored case. A six-tune musical longcase clock and two chiming clocks are also known to be in Russia.
