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 (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.
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)
The memorial stone over Helena Larsdotter (b. 1635) and Mats Hindersson (b.
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.
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.
