Hi Ellen, As far as the reason some Laxtons migrated to the US, I can only speak for my side. John (born 1844), the youngest son of William H Laxton, came over to the US to do mining engineering work in and around Portage PA about 1879. I have a few ship records of him coming and going between US and UK. By 1900, he was living or visiting with his son Frederick, who came to the US about 1890. His daughter Eva married a Arthur Kendrick and they also lived here for some time.
