Hi KarenE and WELCOME TO ROOTSCHAT

HALS Online Names carries 2 items re a will (1824) of John Castle Maltmaker. (sounds really promising)
Norton - The Three Horse Shoes seems to have been run by the Chamberlain Family almost exclusively from 1790 thru to 1902
1790 - 1824 Clarke C (Victuallers Recognizance on HALS)
1825 - 1828 Elizabeth C (Victuallers Recognizance on HALS)
1828 - 1840 ?
1841 - 1851 No Victuallers / Beerhouses listed in Norton
1861 - 1902 Various Chamberlain (Census / P.O.Dirs / Kellys)
It was quite a common sideline/2ndincome for people to run BeerHouses (as opposed to a "full" public house), brewing their own beer(s). Quite often the OH carrying out the brewing.
