Viv, I know this is a couple of years late but I've just started researching the drovers and their routes. I'm in Llandegla, Denbighshire by coincidence and they passed through this village. I managed to get a small book yesterday in Llangollen which is an account of the lives of the Welsh drovers. Only just started it but it tells how some of them actually began their journey in Anglesey and the cattle had to swim across the Menai straits! I had heard this before but this confirms it. The book is called 'Hard Road to London' by Idris Evans and only mentions Birmingham in passing, however, we know they came here and to have a road named for them they must have come pretty often. I believe they came in from this side of town so to have the market there makes sense.
