Hi Mark,
Thanks for the info. I didn't know about the Barnstable Record Office, so that could be useful for the future. Judging by the way my chap moved around, and since I believe he was probably a journeyman, he could have spent some time in Barnstable.
The Somerset Record Office is in Taunton. A lot of my family came from Somerset, so I've spent some time there. They insist that if you are handling original manuscripts there, you have to wear gloves, which they will provide if you haven't any, so I'm always amused by the "celebrities" on the television who are shown handling priceless and irreplaceable manuscripts using their bare hands !
Tiverton, Chard and Taunton were all lace making centres, so no surprise when framesmiths turn up at any or all of them. One of my Quail family married into the Jackson family and settled in Chard.
I tried searching TNA catalogue for Heathcoat, but it said it couldn't find anything. I think it must be me ! I'll have another go sometime and see whether I was doing something silly !
Best wishes,
Mike
