This is the current “working tree” status of the Q-L11515 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-L11515 branch i part of the big tree of paternal lines.

Just an alternative view of MyHeritage auto cluster results. The following link makes a hairball plot out instead of the ordinary matrix presentation.

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. Some how the Q-L804 branch seems to have made it to northern Europe at some point, likely through Siberia. Non YFull kits gets a highly transparent dot in the predicted branch colour that can show the dencity of Q-L804. The Genographic Project (Geno) kits with Q-L804 Geno stoped collecting samples in August 2019 but have captured some Q-L804.

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.

Well known are the settlements of Finns in Värmland but less known are the settlements in Norrland. So here comes a animated map of the settlements over time of Finns in Norrland. (Right klick and choose “view image” or “open image in new tab” to get it Zoomable). The area south of Dalälven is excluded. It makes the close DNA matches between people in this area and Finland more understandable. The map is based on Maude Westins map.

Hans Ersson, 1655, illustrates the impact an individual can have on the genetic make up of a region. 25% of those born 1890-1930 in Sorsele had a strait paternal line to him according to the database Kråken. Quite extrem! To see if there were more extrem cases I made a histogram of the number of “founding fathers” and their number of descendents in the database with a strait paternal line to them.

The maps illustrates the impact of the “Örträsk Finns” on the interior of Västerbotten by three maps showing how their descendants spread. It is based on the database Kråken which is not compleatly finished for all of Västerbotten but it can anyway give a rough picture of how they spread over the land. For illustration three of the founding fathers are used namely: Johan Philipsson Hilduinen ca 1620-1697 Mårten Hindersson ca 1625-1697 Erik ca 1640 only known from his two sons Erik and Håkan The first map shows the proportion of the persons born 1890-1930 who descend from them.

Visited again the old settlements of some of my forefathers. The house on the picture is standing on the place where Erik Ersson (b. ca. 1669) helped his brother Håkan (b. ca. 1670) to start a farm in Örträsk in 1706. It has not been properly dated but might be from around 1750. (Green dot on the map at the bottom) The map below over Håkans farm is klickable for a large map over Örträsk from 1713.
