UPDATE1: y-Haplogroups I1 and R1b in European Countries, plus Ancient Migrations

Here are some new results:
y-Haplogroups I1 and R1b in European Countries, plus Ancient Migrations
I1-"BBA" is the dominant I1 STR cluster/clan in Norway and Sweden. Nearly 50% of Norway and Sweden's I1 population is I1-"BBA". It is also prevalent in other countries such as the Netherlands/Belgium and Denmark. Many I1-"BBA" and virtually all I1-"BBB" people have the L22 SNP mutation for I1d. This is consistent with the L22 mutation originally happening in a "BB" individual before the split into "BBA" and "BBB".
I1-"BAA" and I1-"BAB" (collectively called I1-"BA*") are the dominant I1 STR clusters/clans in Finland and account for about 75% of Finland's I1 population. Those two clusters/clans are associated with the L258 SNP mutation for I1d3a. Due to a back-mutation in DYS511 they could otherwise have been classified I1-"BBA". Within Finland, I1-"BAA" is more likely in western areas (and even across to Sweden/Norway), and I1-"BAB" is more likely in eastern areas. (Note that a DYS459a=7 cluster should be excluded from I1-"BA*".)
I1-"AABB" is relatively high in Ireland, Scotland, England, and the Netherlands/Belgium. That cluster/clan is associated with the L338 SNP mutation for I1f. So far, 16 out of 16 known L338+ people would be classified as I1-"AABB". Up to 10% of I1 people may have that mutation.
I1-"AABA" is particularly high in Wales - but the sample size is low. So far, 8 out of 19 Welsh-ancestry I1 people, or about 40%, would be classified as I1-"AABA", whereas the European-wide rate is less than 10%.
I1-"AAA" is the dominant I1 STR cluster/clan in Europe as a whole. About 25% of European I1 people would be classified as I1-"AAA". There is a slight decrease in frequency from southern to northern Europe, due to the increasing frequency of I1-"BBA" in the north.

UPDATE4: y-Haplogroup I1 Dispersal/Expansion

The map below superimposes the present day range of the various I1 STR Cluster/Clans. It is a guide to the possible I1 Dispersal/Expansion.
One should keep in mind that the range and distribution of all haplogroups in Europe have been complicated by the comparatively recent Migration of "Barbarians" (before about 500 AD) and the Migration of "Vikings" (around 800 AD to 1100 AD). The "Barbarians" were mainly Germanic tribes from east of the Rhine and north of the Danube, comprising of the Goths (Visigoths and Ostrogoths), Vandals, Lombards, Burgundians, Franks, and Suebi etc. Also the Angles, Saxons, and Jutes; plus the non-Germanic Huns from Central Asia.

y-Haplogroups I1 and R1b in European Countries, plus Ancient Migrations within Europe
A concise summary of some of the ancient migrations of the people within Europe is given for general interest, and also to put into historical context TMRCA’s and the various “Frequency by Region” plots.
This report compiles various sources of y-Haplogroup data for the common y-Haplogroups in Europe, and presents them in tables showing their frequency distribution for each region (or country) of Europe. In the case of I1, the proposed I1 STR clusters/clans1 are presented in the same style of table.

Previously known east-to-west increasing frequency trends can be seen for y-Haplogroup R1b, which has been suggested as being related to the expansion of farming from the Near East into Europe during the Neolithic (from 7,000 BC to 4,000 BC) and the subsequent interaction with the indigenous hunter-gatherers of Europe at the time.
In the case of y-Haplogroup I1, whose MRCA may have existed after, or near the end of, the transition from hunting-gathering to farming in Europe, there is a south-to-north increasing frequency trend. The following more recent (as of say ~200 years ago) geographical frequency distributions are of note for the I1 STR clusters/clans:
★ I1-"BBA" is the dominant I1 STR cluster/clan in Norway and Sweden. Nearly 50% of Norway and Sweden's I1 population is I1-"BBA". It is also prevalent in other countries such as the Netherlands/Belgium and Denmark. Many I1-"BBA" and virtually all I1-"BBB" people have the L22 SNP mutation for I1d. This is consistent with the L22 mutation originally happening in a "BB" individual before the split into "BBA" and "BBB".
★ I1-"BAA" and I1-"BAB" (collectively called I1-"BA*") are the dominant I1 STR clusters/clans in Finland and account for about 75% of Finland’s I1 population. Those two clusters/clans are associated with the L258 SNP mutation for I1d3a. Due to a back-mutation in DYS511 they could otherwise have been classified I1-"BBA". Within Finland, I1-"BAA" is more likely in western areas (and even across to Sweden/Norway), and I1-"BAB" is more likely in eastern areas. (Note that a DYS459a=7 cluster should be excluded from I1-”BA*”.)
★ I1-"AABB" is relatively high in Ireland, Scotland, England, and the Netherlands/Belgium. That cluster/clan is associated with the L338 SNP mutation for I1f. So far, 16 out of 16 known L338+ people would be classified as I1-"AABB". Up to 10% of I1 people may have that mutation.
★ I1-"AABA" is particularly high in Wales - but the sample size is low. So far, 8 out of 19 Welsh-ancestry I1 people, or about 40%, would be classified as I1-"AABA", whereas the European-wide rate is less than 10%.
★ I1-"AAA" is the dominant I1 STR cluster/clan in Europe as a whole. About 25% of European I1 people would be classified as I1-"AAA". There is a slight decrease in frequency from southern to northern Europe, due to the increasing frequency of I1-"BBA" in the north.
Some SNP mutations in y-Haplogroup I1 are found to be associated with a corresponding I1 STR cluster/clan. Table of Contents
