Skifferkniven i Storarmsjö, The slate knife in Storarmsjö

This slate knife (skifferkniv) was found in Storarmsjö by Johan Albert Häggström born 1889-10-22 in Ström, Bjurholm while digging a ditch. He is a distant relative to me and descendant of Erik Ersson in Knaften. He thinks he hurt the knife with his spade which might have taken the otherwise common elk head (American:moose) ending of from the knife. The culture that made knifes like this is the “slate culture” Skifferkulturen that had its prime 3300-2000 BC and was also present in Norway e.

Most fertile persons in Southern Västerbotten and Northern Ångermanland

Fertility based on the database Kråken. The area that is covered is maily northern Ångermanland and southern Västerbotten so many fertile people from for example Skellefteå is missing. I know of at least one woman from Skellefteå with 21 children. The woman with most children, Maria Lovisa Johansdotter,Spöland, had her 22 children Nils Petter Hurtig Olofsson, Vännfors, who had 23 children. The male competition ends with a draw between Erik Nyberg Eriksson, Nyåker, and Mikael Mikaelsson, Armsjö with 29 children each, both with 2 partners.

Rh-negativ förbannelsen

(English summary: Link to a paper showing that the Rh-negative blood type stod for a big part of stillbirths and infant mortality clustering within families in Skellefteå.)

Skellefteå har även en mycket stor andel som har blodgrupp Rh-negativ.

Proportion Sami in northern Sweden

Sami in southern Sweden

This is the percentages of sami in the parishes as reported by the ministers. What they reported is “Lapps” and maybe this term has been interpreted differently by different ministers. Maybe there is not a one to one correspondance of the term. White areas denotes missing information. The areas in Värmland, Dalarna, Västmanland and Gästrikland with sami population are wellknown and studied eg by Ingvar Svanberg and discussed at Other interesting areas on the map that stand out are:
