There really isn't much of a difference between the two languages for the exception of some words, phrases, and sentence forming. However, Scottish Gaelic is not recognized as an official language in Europe, or rather the European Union. Why...I don't really know. I believe it was the Anglo-Saxons along with the Danes (Danish/Denmark) that overran the Picts. Scotland for most part had been ruled/owned by the Danes, who spoke a version of German. Now, the Scots language which is different from Scottish Gaelic is more closely related to a German dialect.
FYI....Danes are not Norseman. Norseman refers to Finland, Sweden, and Norway. Also, the term Viking is grossly misused everywhere. The phrase "to go viking" meant to go pirating or plundering. So the Norseman were not "vikings" unless they decided to go pirating or plundering. Anyone could go viking, there was never a Viking tribe or Viking culture.
