I1-SwF cluster / I1-JN38 subclade – status 2015-10-08

SwF is a cluster with ancestry on both sides the Gulf of Bothnia

.Gulf of Bothnia

SwF was first identified by STR matches but recently a couple of BigY kits have made it possible to form a branch in the haplogroup tree defined by the SNP JN38/Y16813. Yfull currently displays two kits, at a new branch after I1-Z2337:

A third BigY kit has just been completed (not at Yfull yet) and a fourth twig has been formed by testing of single SNPs at Yseq.

Explanation of time estimates

A 4100 years since the most recent common ancestor of all men being Z2337+, according to Yfull estimates.

B 750 years since the common ancestor in this split lived, according to Yfull estimates.

C 1350 years since the common ancestor of this split, roughly based on four more SNPs compared to split B and about 150 years per SNP.

D 300 years to common ancestor of split based on Yseq results on CombBED SNPs, JN41-, JN43+, JN44+, JN46+, JN47-. 2 of 5 SNPs are negative over 750 years, dating the split to roughly 300 ybp.

The ancestry of kit #298918 is known back to year 1800, Örnsköldsvik Sweden. The oldest known ancestor of kit #N136156 lived in Viborg, Finland in the late 19th century. Based on this knowledge it is not likely that the split occured less than 250 years ago.

French Q-L804 subclade – trace of Normans?

The Scandinavian haplogroup Q-L804 has been expanded with a branch from Norway to the North Western France, close to Normandy. This happend when the BigY results for a kit with French origin came in last week. The results make it possible to believe that the new French kit has a Norman origin.

The Norwegian kits which are close to the French have their oldest known ancestors in Møre og Romsdal and Nord-Trøndelag in the 18th – 19th century while the French has it’s origin in Mayenne, Pays de la Loire, in the 17th century.

The current Yfull TMRCA indicates that they have a common ancestor about 1600 years before present which means that the migration should have occured in the centuries after the 5th century, with very wide margins. The Normands occupied what’s now Normandy in the beginning of the 10th century. The new French result is not yet included in the Yfull time estimate.

Fransk gren av Q-L804 – spår av normander?

Den skandinaviska haplogruppen Q-L804 har nu en gren från Norge till trakten av Normandie. Förgreningen från de norska ”kusinerna” gör det möjligt att tro att det franska kitet har ett ursprung i norska normander.

De norska resultaten har äldsta kända anor i Møre og Romsdal och Nord-Trøndelag på 1700-1800-talet och det franska har sin äldsta kända ana i Mayenne, Pays de la Loire, på 1600-talet (Trotry de la Touche).

Enligt Yfulls hittillsvarande uppskattning (där det franska resultatet ännu inte finns med) har de en gemensam ana som ligger c:a 1600 år tillbaka vilket innebär att förgreningen bör ha skett under århundradena efter 400-talet. Normanderna ockuperade nuvarande landskapet Normandie i början av 900-talet.

Här finns den senaste översikten över Q-L804.
