Excluding countries like the US and Australia, Britain and Irish/English names and those with ancestors from Britain and Ireland. I've included those 14.5 cM or greater.

Netherlands: 13 matches ranging from 14.8 cM to 27.7 cM
France: 8 matches ranging from 14.5 cM to 22.2 cM
Germany: 7 matches ranging from 14.7 cM to 19.3 cM
Norway: 6 matches ranging from 14.8 cM to 20.9 cM
Sweden: 6 matches ranging from 14.7 cM to 20.4 cM
Finland: 4 matches ranging from 14.5 cM to 16.5 cM
Denmark: 2 matches ranging from 16.2 cM to 16.6 cM
Dominican Republic: 1 at 20.2 cM
Iceland: 1 at 18.9 cM
Poland: 1 at 15.5 cM

I haven't gone through my other family member's matches but I did get an email quite recently that my great aunt has a 34.4 cM German match who has a tree with all her ancestors in Germany.

Well, I have no connection to mainland Europe. But I have a number of 'close' matches'. My matches are filtered based on having foreign surnames, not by dna type as Germans etc can record English ancestry without any known English ancestry.

Norway: 14.
France: 9.
Denmark: 9.
Sweden: 7.
Germany: 2.
Netherlands: 4.
Switzerland: 1.
Finland: 1.
Greece: 1.
Greenland (danish surname): 1.

To me the question is why do people get such results? Are the underlying assumptions to our autosomal matching methodology faulty? The results sure seem to be incongruous.

Thanks, but show me the ancestor in common. With so many people getting results like that, you would think that someone would be able to find a common ancestor.

My dad has two +40cM French matches but they also are in a pile up region..actually 2 of them. Matches are chr 15, 20-34.

Chr 15 20-25, 27-30 are the common pile up regions.

That people from all over the world pile up in the same areas I find interesting.

What is a pile up region?

"Pile-up region" is a colloquial term for a range of base pairs on a particular chromosome where population genomic studies have shown that a whole lot of people--as in an abnormally large segment of the population--share a matching segment of DNA. This might be the result of a common descendancy stretching back prior to the genealogical timeframe or, in some instances, the result of an area of a chromosome that includes an active, protein-producing gene that nature doesn't much mess with. An example of the latter is a stretch on chromosome 6 in the HLA (human leukocyte antigen) area that's involved in the autoimmune system. Areas like that can't mutate too much, or the organism loses its bright prospects for the future. Most of the SNPs tested in current autosomal DNA testing for genealogy fall outside the places that house known protein-producing genes, however. Not all, but most.

Matches in either kind of pile-up region (or that significantly overlap same), though, probably should be considered of lower value genealogically. It may indicate some deeper, older relationship--as in clan or regionality back several hundreds of years--but a smallish segment that falls in a pile-up region likely isn't very useful in the search for, as an example, a 6g-grandparent.

I haven't gone through my other family member's matches but I did get an email quite recently that my great aunt has a 34.4 cM German match who has a tree with all her ancestors in Germany.

My great aunt got another new one today. She shares 27.3 cM with a French man with only French ancestors in his tree. My great aunt gets 100% Irish, Scottish and Welsh while he gets 0%.

As an aside, she also got a new match with all her ancestors from Ireland. However, she gets 11.9% Baltic, 1.2% Italian and 2.1% Mesoamerican and Andean.
