My name is David MacLellan, my ancestor was James MacLellan, he had bothers John and William who came on the Hector. James came over later. They all settled in the Pictou, Nova Scotia area. It seems like you are talking about the same family. I have information about the family in Canada and California but not so much about Scotland. Contact me if you get this message. I would be interested in sharing information, especially if you have any about the family in Scotland. I plan to go there this May.
thanks David
