A case study across multiple generations.
One of the exciting aspects of autosomal DNA testing is that it gives us the opportunity of assigning segments of DNA to specific ancestors and then tracking the inheritance of those segments over time. To date the only match...

I like the maps in this latest blog post from AncestryDNA showing the regional distribution of "Scandinavian" and "Europe West" DNA amongst AncestryDNA customers in the UK.
This post was co-written with Peter Carbonetto, Ph.D., Computational Biologist at AncestryDNA For every AncestryDNA customer, we estimate the ethnic origins of their ancestors from their DNA sample—what we call a “genetic ethnicity estimate.” AncestryDNA customers can currently trace their ancestral origins to specific parts of the world, including 26 regions across Europe, Africa, Asia,… Read more

A Lincolnshire origin would certainly make sense if is a Scandinavian surname. I note you're researching the surname Rosling. I presume you know of the statistician Hans Rosling. I love his talks on statistics. It's not a subject that you would expect to be interesting but he explains it so well.

Howard Mathieson reviews another Origenes case study and finds a number of "serious issues".
Scottish Origenes claim to define a surnames “genetic homeland” by identifying geographic areas where farmers with matching surnames cluster. In this case a small area with a five mile radius in northern Dumfriesshire is identified as the McMillan's "genetic homeland”.

I suspect there will be many more stories like this in the years to come.
HO CHI MINH CITY, Vietnam -- Vo Huu Nhan was in his vegetable boat in the floating markets of the Mekong Delta when his phone rang. The caller from the United States had stunning news -- a DNA database had linked him with a Vietnam veteran believed to be his father.

I've just realised that I somehow gave the wrong date for mitochondrial Eve. I meant to say 200,000 years ago not 2000 years ago!

+Puzzled Researcher I've always had the impression that the Colonial American families are huge and I often hear of gateway ancestors with thousands of descendants and whole projects or websites set up to document their descendants. We don't tend to see UK trees of the same size though I've never seen any studies that have tried to do a comparison. My guess is that we would need to get comparatively more people tested in the UK before people start getting fortuitous matches. I don't think the take-up of the AncestryDNA test is going to be so great here because of the high price in the UK (almost 50% more than FTDNA's Family Finder). £65 is affordable but people will think twice about paying £119. The 23andMe test is also more expensive (£125) but at least with the health and trait reports you get more value for your money.

DNA testing might help in this case.
A man from Plymouth who was abandoned as a baby almost sixty years ago is appealing for public help to find his natural mother. Robert Weston was found by a stranger in a cinema toilet when he was just three weeks old. Andy Bevan reports.
