Hello Harold Corkhill, good to hear from you. I suspect we have the same info re the Ferraby family - is it the tree that was prepared by Frances Spurgeon? I also have masses of information on the Da Costa Andrade family - I believe Ada Florence Andrade is our mutual great grandmother? Since my posting earlier today I have come across another posting from another Corkhill relative - who may be your sister or cousin (not sure from what she wrote.).
Looking forward to hearing from you, Christina (with an a on the end!)
