A new article taking place before the study tells that at least four of around twenty samples in a southwestern Iron Age cemetery (Luistari) belonged to the male haplogroup N and no other haplogroups existed. If we assume an even distribution between females and males, we can say that at least four of ten males carried haplogroup N. The probability for all ten being N is very high and suggests about quite a dense local population. The article doesn't give information about detailed haplotypes, so we can't figure the origin or populational connections. Ten of twenty samples got maternal haplogroups, some showed eastern and some western kinship. A bit mysteriously the article suggests that maternal haplogroups have more similarity with modern eastern and northern Finns than with modern western or southwestern Finns. Does this mean that present-day western Finns migrated later? Or does this mean that Iron Age Finns married women from eastern and northern parts of the country? Researchers were able to specify some phenotypic details of four men and one woman. They all were blond. Three of N samples showed mutations linked to the disease Dupuytren's contracture, also called in Scandinavia as "Viking disease". This is a huge amount, even if we suggest N=20. Did the Vikings belong to the haplogroup N?
Luistari is a large Iron Age cemetery in Finland with a lot material artifacts like jewellery and weapons and significant even in an European scale including over 1300 burials.
