Hi there
Just tracked down a marriage certificate for 1900 and the bride's father is described as a "traveller" . 
Interestingly from same certificate my great-grandfather, who the family only ever knew as a miner/coal hewer from a family of miners had his profession recorded as  "baker". 
So far my familys occupations are a strange mix - canal boatmen, miners,  gardeners, cofters, weavers and a grocer. 
On husbands side brickmakers, horse-drawn omnibus driver ( a GRAY driving 2 grey horses),farrier, groom, and a signalman on GWR...
