In the 18th Century, there was a huge trade between Scotland and the Nordic countries. I read a thesis, cant remember if Masters or PHD on the economy of Scotland prior to the 45 and one of the biggest imports was timber for houses. So its perfectly understandable for a Scot to come here from that area. There was an entire Scot's brigade in the low countries, I have ancestors who were Scottish, but came here from Gotland.....
