Haplogroup I is found almost exclusively in Europe where it is represented in about 20% of the population.  Overall, Hg I has a broad European distribution, from the British Isles east to the Ural Mountains of Russia and south to Anatolia and the Mediterranean Sea, but its strong geographic concentration in northwestern Europe has led Hg I to be nicknamed the "Viking" haplogroup (though some consider R1a to be the only true Viking haplogroup).

I1 is the most common subclade of Hg I.  Geographically, it is highly concentrated in northern Germany, Denmark, and southern Norway and Sweden.  A modal haplotype for all of I1 would not be meaningful because the different varieties of I1 have not shared a common ancestor for thousands of years, but key markers do unify the subclade (highlighted in red in the tables).

Among European haplotypes, DYS455=8 is virtually exclusive to I1 and YCAIIa,b=19,21 is universal in I1 (table cells highlighted in red).  With one exception (I1d), the subclades of I1 are rare to the point of not being useful, but no other SNPs subdivide the otherwise very large I1 group.  In lieu of useful SNPs (the search for which is ongoing), varieties of I1 have been defined by Nordtvedt based on STR haplotypes.  Another useful marker in this subclade is DYS511 (highlighted in royal blue in the tables), which has a value of 10 in the Norse and ultraNorse varieties and a value of 9 in the AngloSaxon varieties.  Your project administrator recommends all I1 individuals upgrade to 67 markers to pick up the result for this marker.  DYS462 is similarly useful and can be ordered as a custom test from FTDNA.
Ken Nordtvedt is the guru researching Hg I subclades (see his Excel spreadsheet).  For a table showing modal haplotypes for his Hg I varieties in FamilyTreeDNA marker order, please also see my HTML transcription of Nordtvedt's spreadsheet.  Jim Cullen has develpeda predictor for the varieties of Haplogroup I, and I have used it to made the determination below.  In some cases, the predictor was not able to make a firm prediction, mostly in cases where not enough markers were tested.  I urge all participants to upgrade to 67 markers to get a solid prediction, and if you're predicted to be I1d, to be SNP tested for L22.
I1-AngloSaxon is the most common form of I1.  It is most frequent in the Netherlands, northwestern Germany, and Denmark and is present at lower frequencies in eastern and southern Germany, southern Sweden, and the British Isles.  I1-Norse is the most common I1 variety in Sweden and Finland and is the second most common variety in Norway and Denmark.  Like I1-Norse, I1-Norse-D is most common in Sweden, Finland, Norway, and Denmark, but the "D" variety leans toward Denmark (the value of 12 at DYS439 is what most distinguishes the D variety). I1-ultraNorse has its greatest frequency in Norway where it is the most common form of I1.  It is the third most common form of I1 in Sweden and Denmark (after I1-N and I1-AS); it is found only sparingly in southern and eastern Europe.  "Missing Link" refers to the link between AngloSaxon and Norse; "Transitional" refers to forms transitional between AngloSaxon and Norse.
I frankly have a problem with the way Nordtvedt has established some of his varieties of I1.  The issue is technical and has to do with his clades not necessarily being monophyletic.  This problem rears its head with uN (ultraNorse) being both M253 and L22, which doesn't jibe with uN being a clade.  However, that need not really concern us here.  The important thing is that, as clusters (not clades), they are useful.

#12656 has been tested at both FTDNA (Markers 1-25) and at SMGF (Sorensen Molecular Genealogy Foundation — for markers tested only by SMGF, please scroll to the right).  He has a rare haplotype with no full or even near matches in the FTDNA, Ysearch, or SMGF databases.
Cullen's predictor gave these as the highest probabilities for his variety:  I-M253-1313 =>31%, I-L22-N =>26%, and I-L22-NuN-14 =>23%.  Your project admin recommends upgrading to 67 markers to get a solid determination, plus deep SNP testing to determine his status for L22 because, despite the slight edge given AS1313 by the predictor, I'm inclined to think I1-L22-N is correct.

This individual transferred in 12 markers from the National Geographic Society's Genographic Project, then upgraded at FTDNA to 37 markers.  Our subject's 37-marker haplotype is unique, with unusual values for three markers (purple table cells).  He does have some 25/25 matches with individuals surnamed MARTIN, and a 33/37 match with the only one of these MARTINs who has been tested at 37 markers.  If their 12 or 25 marker haplotypes were common, I wouldn't make much of a 33/37 match, but given that these are the only individuals with this rare 25-marker haplotype, a distant connection seems likely, though possibly too distant to find on paper. 
Cullen's predictor gave these as the highest probabilities for his variety:  I-M253-ASgen =>15%, I-L22-uN1 =>14%, I-L22-NuN-14, =>14%, I-M253-AS10 =>13%, and I-L22-uN2 =>11%.  Your project admin recommends upgrading to 67 markers to get a solid determination, plus deep SNP testing to determine his status for L22.
The fact is that it can be difficult to place someone whose haplotype is unique, at least until the database gets larger and he ceases to be unique.  But the bottom line is that anyone surnamed JENSEN — by far the most common surname in Denmark — has to be glad their haplotype falls at the other end of the frequency distribution!

#N33753 transferred in 12 markers from the National Geographic Society's Genographic Project.  Our subject has a typical I1-AS haplotype, except for an unusual value for DYS439.  At 12 markers, he has dozens of matches, and his 9-marker haplotype is the most common 9-marker haplotype in Denmark.  Your project admin recommends upgrading to more markers to gain more separation.
Cullen's predictor gave these as the highest probabilities for his variety:  I-M253-ASgen =>16%, I-M253-AS1 =>16%, I-M253-AS8 =>16%, and I-M253-AS3 =>16%.  Your project admin recommends upgrading to 67 markers to get a solid determination.
