My 4th great grandfather William Symons had his occupation in Helston, Cornwall described at least half a dozen times in christening records and marriage certificates of his children and his own death certificate as being a Wine/Spirits Merchant/Dealer (but never as an Inn Keeper). This was mostly from 1829 until his death (aged 55) in 1840, but also once in 1813 - in between he was usually recorded as being a Grocer (or Shop Keeper). His widow Alice (nee Rutter) appears, from the 1841 Census and the 1844 Pigot's Directory, to have continued to run the business at Coinage Hall Street for at least four years after his death.
I am picturing that he/they probably had a shop with a "liquor license" rather than him/them running a pub.
Were "liquor licenses" required in that place and time and, if so, are records likely to have survived, that I could use to try and locate his/their precise premise(s)?
