Mr Jack Martin
Doubtful, Blethyn’s telescopes date from around 1650.
Where did you get this information from ?
Its possible he was a relative of John Bleyghton a mathematical instrument maker in London around 1624-54. He was succeeded by his son John II. They also signed with the names Blaton – Blyton – Blighton.
Thanks for your efforts.
