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.
I made a map of the YFull kits with province listed for the Scandinavian countries and Finland with the basic idear that one kit should be one point. Mainly as an experimental alternative to other maps for showing the geographical distributions of the haplogroups. To avoid over plotting each point searches for a free space to be plotted and can also adjust size to squese in. This causes the ball shapes in especially Finland as most points are located to province landmass centroides.
English summary: Left blue-shaded area “Hersesio” = Herses lake? Right blue-shaded area “Terminus Regii Helsingici” = Hälsinglands old border.
När jag kollade på gamla kartor hittade jag det intressanta namnet “Heresio” vid Bureälv strax söder om Skellefteå (vänstra blå-skuggade området). Det skulle kunna vara en syftning på någon “Herse” som förekommer i Bureätten, alltså Herses-sjö. Det finns ju i områder andra namn som troligen har anknytning till Bureätten som Falmark. Hittar ingen motsvarighet på moderna kartor men kanske kan det vara Bursjön nära Bureälvens utlopp som bytt namn.
