Thanks! I did wonder why someone would register for this. In my family of the Voyce, the father Thomas Voyce was a miner as were several of his sons though they immigrated to the US. One son Ben, was managing several pubs (Bird in Hand) and yet he also registered as a freeminer and that's why I wondered why he would do so. He did work in some US mines before returning to Forest of Dean. Thomas Voyce's family lived on broadwell lane in Coleford and I was told there was a mine at the end of the road when we visited a few years ago.
