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 (http://www.xn--krken-nra.se/kr%C3%A5ken/) 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.
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.
(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.)
När jag har släktforskat på Skellefteå släkter har jag märkt att det verkar som att det vilar en förbannelse över vissa familjer genom att en stor del av deras barn var dödfödda eller dog strax efter födseln. Skellefteå har även en mycket stor andel som har blodgrupp Rh-negativ.
This is my link back to the big Sursill, Arctophilacius and Calamnius family. The link is not yet confirmed by DNA as there are two conflicting DNA tests of the paternal lines from Petrus Arctophilacius at present.

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.
