Thank you Averil and Donna, Sue and Jean.
And Averil thanks for e-mailing the tree. Yes I know it has to be proved yet and I will go back to museum this week some time.
I worked out who the elderly lady is that said the Cains were from Camlork. She is Lydia's daughter and if I find she is wrong, i'll go and hit her with a wet kipper (only joking).
