As I understand it, there are rather many descendants of the so called Kemi Sami. A very few of these, if I got it right, see themselves as Sami, and a few of these and possibly some others with Kemi Sami ancestry have applied for registration in the voting register of the Sami Parliament of Finnish Sapmi. A very few of those have been approaved, but with much Sami resistence. As it is, it seems like some or all of them may be thrown out again. However this goes, it is fine to me if some of Kemi Sami ancestry see themselves as Sami and perhaps even get accepted as it. A very few of them also, as I undertand it, have much to do with occupations and culture associated with the Sami.
Apart from that, in and close to the former Kemi Sami areas from Kuusamo in the south and north, there seem to be much Kemi Sami ancestry in (many/most/all? of) those with older local ancestry. If this is true, I guess it is due to extensive endogamy and an at least initially limited influx of Finns (including Karelians). Anyway, these people and areas have both Finnish/Karelian and Kemi Sami ancestry, and it therefor would seem right if these people and areas should be able to look to all sides of their ancestry even without any wish or possibility of being seen as Sami. That is, if the areas and people should wish so, they should be able to lift forward a mixed background, including some symbolics. Those prefering to only lift forward Finnish background would of course be free to do so, and those perhaps able to just look at Sami background could perhaps do that too, with the conflicts associated with that. Of course, lifting forward Kemi Sami ancestry could be a problem in those areas, with conflicts both with Sami, more Sami cultural Kemi Sami descendants, and some people in more profiled former Kemi Sami family clans.
And then there are people like me, with only two 'confirmed' Kallung/Callung (Callungi/Kallunki) lines from the former Kitka Siida of Kuusamo-Posio, and by estimate at least 2% distant Sami ancestry lines and at very most 10%. That is people of some 'confirmed' and/or likely older Kemi Sami ancestry who due to poverty of the ancestors or other reasons, have ended up far from any ancetral Kemi Sami Siidas. For us it is perhaps like for a Dane having some older verified and/or likely German ancestry or for a southerly Northern Finn having some or much of older Savonian and ultimately Karelian ancestry. Most of those would not consider themselves German, Savonian, or Karelian, or be considered as such, but there would usually not be any problems with expressing this background and even using some of its symbolics related to personal and regional background. Descendants of Forest Finns seem to be able to do this without having any really kept connections or real knowledge of Savonians etc, and so do descendants of the Wallon immigrants of the 1600s. Though, any weak Sami ancestry is seemingly sensitive and offensive, so one, as it seems, better not mention it or think of it, or?
Myself, I do not use any obvious national symbolics, since I am opposed to the formulation of some of these ideas. Then strictly speaking, I am not a Finn or Northern Finn, even if about half my known historic ancestry is from Oulun lääni and nearby areas. As I don't speak Finnish, due to it not being correct to use immigrant (or minority) languages some decades ago, so I cannot really be a Sweden Finn, not even with Finnish ancestry, Finnish citizenship, and some older likely ancestry in the now 'Swedish' part of the Tornio Valley. I may be seen as Swedish based on connection and citizenship, but I likely don't have much Swedish ancestry, and none of it close. Half my ancestry is from Denmark (with a little possibly from Germany, Sweden, Finland, Norway, etc), but I am seldom considered as Danish, especially not by Danes. I also have lived in Norway during many years and on that ground is a citizen of Norway, but even though seeing me as a member of the community while living there, few would have seen me as Norwegian. The ideological core of the Norwegian Party would also argue strongly against having multiple, or mixed national (or identity) backgrounds, and for the connection to the Norwegian social club through its countryside traditions. For this reason, this Norwegian Centre Party core argue strongly against the lacking qualities of us having multiple citizenships.
Anyway, backgrounds shouldn't have to be hidden even when they would upset some people in some political or ethncal group.
PS! I find it strange that the noaide (and his objects) found at the centre of the former Kitka Siida (in 1970) seemingly to such a little extent is seen as being connected to likely heavy descendants of his likely kin (and possibly even him) in present day Kuusamo and Posio and to such a high extent to present day Sami (groups) likely only distantly connected to him and the former Kitka Siida. One could also wonder why former Forest Finn areas in Sweden and Finland can lift forward this background, while Kuusamo and Posio possibly could be on sensitive ground if and when they lift forward local Sami background of the former Kitka and Manselkä Siidas.
