Hello all
I'm also searching for glassmakers in Dumbarton in the 18th and early 19th C. Will get the booklet recommended.
I'm researching the Hartley family who eventually moved to England and were owners/senior managers at various glassworks (Nailsea, Wear Glassworks, Pilkingtons) in the late 19th & 20th c.
If anyone has any further information or advice I'd love to hear it.
Thanks
Maggie
