Yes, my name is Grace. I do remember messaging last year, but I am not sure with whom. I guess that it's you :).
I have a family tree that goes back six generations - it's part the info I have, but I cannot put my finger on where I put it. I did meet the author of the book back in 1985. He was introduced to me as my cousin. I believe, at that time, he worked at a lighthouse. I don't have the book, but one of my aunt's has it. If I cannot locate the tree, I will contact one of my cousins who I think has a copy.
