I once made a list of some possibles on the high street - think I got to 26 pubs!!
I'm hoping one day some more real ale fanatics will emulate the Norfolk Pub site and list the history of every tavern with tenant landlords and ales sold. I'm pretty sure that at least one inn in the Merthyr region would have been at one end of the east/west and north/south drovers trails and wouldn't that be good background information for fam. history.
