Hi Cornish
So sorry to hear about the RSI, how awful not to be able to use the computer! Hope it starts to get better soon.
My mum is a Craze, and my cousin has been researching that branch of the tree. Any additional information would be great. Do not attempt to reply, I am just leaving this message in the queue for when you get better again

I also notice you have a "Williams" in your list of names, from Cornwall and South Africa areas. Just wondering if you have an Ellen Williams, sister of Thomas John Williams of St Erth, Cornwall. In his obituary she was listed as living in South Africa. Just thought I'd ask on the offchance. Again, do not reply until you are better, it is not urgent. Oh dear, I sound very bossy.
All my best wishes for a speedy recovery, from rainy Cornwall.
