I myself do something different (a classless system), but a short answer is: sorcerer, barbarian and scout, respectively. For the scout you can choose to either keep or remove the small size stuff (weapon restriction and Dex bonus)
See, that's what I was thinking, too, but there was a definite lack of anything resembling the typical barbarian in Europe around this time. Oh, but there were the natives of the Canadian and American colonies! They could be classed under 'barbarian', I suppose. And they did bring some of these folk back as exhibitions and the like. Again, the class would require some re-working, but it's doable with very little effort.
Sorceror is still... ehhhh. I dunno, it's hard to picture a sword slinging spell weaver in any sort of modern or semi-modern historical context. Still falls in the land of Moorcock and high fantasy/swords and sorcery. Can't imagine a European historical equivalent from around the 1600's.
Edit: Brotherhood of the Wolf and the human zoos of Europe are examples of possible ways to introduce the barbarian class back into Europe. Granted the human zoos were something that came later on, but there are several well documented examples of natives from the colonial settlements being returned to Europe and placed on display in the palaces of kings and other members of the aristocracy. One fellow was even de-fleshed after he died, and his remains put on display in a museum. I think they only recently got around to interring the poor fellow.
