My ggf was a blacksmith in Co Tyrone, Ireland. There is a list of all the blacksmiths registered for each county in Ireland in a sessional paperfor a House of Commons proceedings. I found the papers in Kew PRO - there were none for Tyrone and none for Londonderry but a whole heap for Donegal. I spent an hour or so transcribing the Donegal list only for someone to tell me it has already been published somewhere. I am happy to forward it to this list or to anyone who wants a copy.
