Ancestry Finder tables

Here are the results of Ancestry Finder. It uses self reported ancestry from users of their Grandparents nationalities. So the table showing 4GP means all 4 Grandparents are the same nationality. The list can go down to 1+GP meaning it could display matches who have Grandparents from four different countries. A word of caution is that just because Grandparents were born in a certain country, it doesn't meant they are native to it. An example might be French people born in Britain. So it's best to check for more than one match. Size of cM's in important too-the closer to 5cM, the more likely it's either very old or just coincedence.

At 4GP's:Known ancestry is British and some Irish, so the first two boxes match known ancestry. Iran has featured with other people and it's only 5.1cM so either the person has some West European ancestry or it is ancient.

At 3 GPs (so 3 from same country, 1 from different) the top 5 is the same however my 7th cousin who is 1/4 Finn 3/4 Swedish now appears.

At 2GPs same top 5 but now have a match to someone who is half Swedish half Norwegian.

At 1GP same top 5 but now have a match to someone who is Danish/American/Swedish/Swedish-would love to know about them as the amount they share would make them 4th-5th cousins!!!

There are some Polish matches which seem to overlap-in one place there are two matches and they describe their Grandparents as Polish/Polish/Israel/Romania and Poland/Poland/Ukraine/Ukraine the other matches in a different place are Poland/Poland/Unknown/Unknown (half Jewish) who overlaps with an American who is English/Italian/Polish. I wonder if we all share Polish ancestors from way back as that seems to be the common country?

There is also a 7th cousin who is half southern Slavic half unknown but was born in Croatia...not sure about the migrations of the southern Slavs...I wonder if they settled in places like Hungary and mixed with central Europeans?
