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.

This is the current “working tree” status of the Q-Y11515 branch that has spread over much of northern Scandinavia. (Right klick and choose “view image” or “open image in new tab” to get it Zoomable). Green squares mean that we have at least two kits leading to the same forefather. The orange ones are of course important to get tested to confirm the correctness. The Q-Y11515 branch i part of the big tree of paternal lines.

I have made some experiments with predicting major haplogroup branch (U5a1, U5a2, U5b1, U5b2, U5b3) using machine learning techniques. I have tested multinominal logistic regression (“multilogit”), random forest, discriminant analysis and K Nearest Neighbor. So far I have had best luck in classification accuracy with multinominal logistic regression so I will present those results. Only the HVR1 region is used as information and the models are estimated using those kits that have a definite haplogroup.

This is the geographical locations of the YFull kits of the interesting branch Q-L804 with closest relatives among the American indians. Non YFull kits gets a highly transparent dot in the predicted branch colour that can show the dencity of Q-L804. Some how the Q-L804 branch seems to have made it to northern Europe at some point, likely through Siberia. The common origin with native americans is likely in Siberia or Beringia.

This is the current status of the family tree of Q-L527 based on the data at YFull (Updated 2020-01-01). Two interesting kits from Belarus and Ukraine on old branches. They might give an indication of a possible migration route to Scandinavia. The main expansion in number of branches of Q-L527 seems to be before the viking age. I have estimated branch length in years with the Ape package in R using maximum likelihood and the “strikt model”.

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.
