Hello, Many thanks for the information about William Gill. The only other "Gill" on my index at present is James M. Gill working in Wakfield, West Riding Yorks in 1862. This is geographically quite a jump, but I would be interested to know if there is a family connection. Such a small percentage of people were corkcutters that there is often some link in families.
Other surnames that I have cropping up in Exeter over the years are Bartholomew Worth (c. 1797), Wm. Mortimer (1822) John Tothill (1822 and 1844), John Stockham (1844) and Bailey (1895).
More significantly I have William Gale mentioned as a master in Exeter in 1882 and 1884. He is also running a business in London at Walworth at that time. Could this be your William Gill or maybe just a coincidence?
Best wishes
Corkcutter
