the "Dalarna" second man (right, up) has nothing specially Spanish; he has some cromagnoid-like features for bones, what can be found allover Europe, if not always so rarely; sure he doesn't seem typical Swedish, even less than the other man; by the way, I read somewhere the most of slaves in Sweden had been found in Uppsala region, so not in Dalarna, but close enough (East); Where is their traces todate, I dont know? Where are the Walloons descendants?
as a whole, Dalarna people are (or were in the 50's) in a rather subdolicephalic region of mean stature for Sweden, rather light haired if not at the maxi for Sweden, so not a so special pop at first sight, if my records were correct;
concerning Saami, todate they are very mixed and lot of them, not by force "Germanicised", are rather mixed with other Finnic people more akin to Finns, so often light haired; the first Saami were very darker haired, and very smaller.
The nick6899 head evoke me nothing of precise: 'dinaroid'? no, in any way! very little 'alpine' if any, some light psuedo'nordic' input, more of something 'danubian med' ("gentle med" of Anatolian pre-Iran Neol origin, dominant among first EEF); the nose is not typically mediter, rather nordic+danubian (but how "pure", noses can need so much different genes) ; the height of skull evoks "danubian", but the frontal profile and browridges evoks something slightly 'brûnnoid' (parlty, gracilised!) which could be confirmed by the too light and too large irises for true 'nordic' (so my 'pseudo-nordic' is rather something of 'brünn' trend; only a personal religion, this correlation of 'brünnoid' with large pale pure blue eyes! But they are found rather among the lighter haired lighter eyed larger eyed, meso-subbrachycephalic people of North-East Europe, where a seemingly pre-'nordic' archaïc input seems stronger; this kind of light hair and light large irises are not found to much among Welshes where the 'cromanoid' input isn't negligible.
all that is kind of folklore because we know that there are associations of traits which can have had a collective reality at some time for a relatively limited span of time, these traits being dissociable one from another with time.
You can laugh as we can laugh at precise typology on modern people of multiple ancestries (already in ancient times...). Have a good time!
