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.
Here is a more detailed view of the North Swedish subbranch Q-Y45428 of Q-L804. All nine boxes at the bottom are kits tested at ftDNA and verified by “paper research”. Of the nine kits, eight can be followed to Erik, the father of Erik Ersson (6 kits) and Håkan Ersson (2 kits). Erik has made a big contribution to the population of Västerbotten and probably most people in the region can find him on their pedigree.
My pedigree. A lot of inbreeding going on in Västerbotten due to the rapid increase in the population from a small founding population. The part from Leksand, Dalarna has on the other hand very little inbreeding.
Some of Mikael Mikaelssons (Mickel Mickels’n, Gamm-Mickel) decendents that remaind in the area. He had 29 children in 2 marriages. Rapid increase in decendants and a lot of inbreeding in the following generations. Mikael Mikaelssons farfarsfar (Great grandfather) was Erik Ersson.
