Hi Roger,
Thanks again for the info. Yes, I've researched the topic quite a lot and the Quail name that you recall on a list would have been a posting of mine.
The lace industry in Chard built up after Heathcoat's patent for a bobbin lace machine expired in 1832. I suspect that my ancestor worked for Joseph Wheatley, but I can't be certain and so I'm always on the lookout for any other lace manufacturer that he could have worked for. As far as I know, Boden did not set up in Chard. I suspect Ambrose Brewin didn't either, as it would have been in competition with his father-in-law, John Heathcoat, but you never know in this game !
Best wishes & thanks again,
Mike
