David, I've just read all of the lines of inquiry on this name and it seems that you are all chasing Radfords from USA. I didn't realise that when I first replied, but I have enough trouble trying to track them down in England !!
I did have 2 females (Alice & Elizabeth)leave Uk at the turn of the century to go over the pond, but thats all I know, I cant imagine I will get any further.
