Good to get a response after all these years (!) but I'm afraid I don't think there is any connection. That birth in Blaina really was an isolated one. One of John's uncles was also born there, but I think it's because the families travelled over there for work occasionally when there was none to be had in the Forest of Dean. None of your names ring a bell - and mine were still in St Weonards Herefs when yours were in Wales. Sorry.
