It's great to get your message! I can definitely give you proof of Jane Williams going to the USA. In 1945 she and most of her children (with their families) sailed to New York and then settled in Cambria, Wisconsin. I have copies of the ship's manifest. I have Jane Williams' land records, will, and pictures from the cemetery where she is buried. There is still one of her descendants living in her home in Wisconsin - the farm is named Bodwrog!
I would love to share information with you. I will send you a more detailed message to your personal address either later today or tomorrow.
