Sorry for delay in replying to your post Yvonne - just returned from holiday abroad. Can you please give me approx dates for your great,grandfather. I thought I had every Nippers in the UK (and beyond) in my tree and I do have a couple of Sarah Anns but no marriage to David Williams. Perhaps you can fill a gap in for me. I have no knowledge of any incidence of haemophilia in the family and I have checked with the Canadian arm of the family who also have no incidence.I will continue to ask around - most of the family is now in South Wales, Yorkshire, Canada and a few in Australia. Best wishes, Lawrence.
