What do you mean by that? The greater migrations occured around 1600 or later, when we are talking about movement of Finns to Sweden, and I do believe that the very greatest movement of all was the one that started around 50 years ago. If you would like to contest any of that, then you have the burden of proof for your claim

The first big migration of finns started during the reign of Gustav vasa.`During the 1600 a lot of finns arrived yes but more arrived 1400-1500.i concur with you that. The greatest movement of Finlanders to sweden started 1950-1960.


btw facts in swedish about finnish migration to sweden

Finsk invandring till Sverige har ägt rum sedan tidig medeltid och har ett samband med att Finland, under 1100-talet blev en del av Sverige. Från 1300-talet ökade invandringen successivt, fram till slutet av 1500-talet. Fram till omkring 1570-talet hade finnarna invandrat via Stockholm och Gävle, till landskapen norr om Mälaren. Speciellt var detta markant under Gustav Vasas regeringstid. Det var finnar som förekom både på landsbygden, som i städerna. De var jordbrukare, drängar, smeder m.m. Många sökte sig till Bergslagen, med sina gruvor och bruk. Gustav Vasa bokstavligen rekvirerade och dirigerade finskt arbetsfolk till kronans gårdar och bergsindustrin.

Movement from western Finland during the great northern war was very likely to a great extent and possibly even exclusively Finlandswedish, or do you have any proof of the opposite?

exclusively finlandswedish? Do you have any proof to back that up?
,btw i wrote western finland. So it would not have surprised me if some of them were Finlandswedish.

The source about Östergötland does not distinguish properly between Finlandswedes and Finns, and hence it is unclear what it is saying, but the names that are explicitly mentioned are overwhelmingly Swedish

Overwhelmingly swedish?a lot of finns had Swedish sounding Names during the Swedish rule.
