Haplogroup I is found almost exclusively in Europe where it is represented in about 20% of the population, though subclade I2 is decidedly less common than its sister clade, I1.  It's difficult to generalize about I2 because it contains a number of geographically distinct subgroups.  One group of I2a was initially concentrated in the Balkans and is called "Dinaric" (for a mountain range there, the Dinaric Alps), from which location it dispersed with the retreat of the last ice sheets.  Another group is found around the Baltic and North Sea coastal areas, another in the British Isles, and another in Sardinia and Iberia.  The root clade of I2b is uncommon, with a probable origin from an Iberian glacial refugium from which it spread widely in western Europe.  The main variety of I2b, dubbed "Continental," is most common in northwestern Europe, southern Scandinavia, and Britain.  Another group, "Isles," is almost exclusive to the British Isles, with a concentration in Scotland.

Unlike Haplogroup I1, which is universally 8 at marker DYS455, Haplogroup I2 is usually 11 at this marker (sometimes 10 and rarely 9).
So far, eight members of Danish Demes are some form of Haplogroup I2.

Cullen's predictor gives a 50% chance of being Din-S and 50% of being Din-N.  Upgrading to 25 markers would presumably narrow it down to one or the other.  This individual has no matches in the FTDNA database.  His best matches at Ysearch are a few at 10/12, and his best matches at SMGF are a few at 9/11. 
FTDNA deduces his haplogroup to be I-P37.2 (I2a).  Your project admin recommends deep SNP testing, especially given that his 12-marker haplotype appears to be unique.

#82373 has a rare haplotype, with no matches at any level in the FTDNA or Ysearch databases.  Cullen's predictor gives him a 68% probability of being I-M223-Root2.
Our subject has opted for deep SNP testing, with these results:
P19+ M170+ M258+ P38+ M223+ P37.2- M161- M26- M21- M227- M253-  M307- M72- P30-
The first four positive results prove our subject is Haplogroup I.  The fifth positive result proves he is I2b1.  The first three negative results confirm that he is not any form of I2a.  The remaining six negative results confirm that he is not any form of I1.
UPDATE:  Our subject has taken the I2b test bundle at EthnoAncestry, with these results:
S23+ S24+ M223+ M284- M379- P78- P95-
The positive result for S23+ proves he is I2b; the positive results for S24 and M233 prove he is I2b1.  The negative results for M284, M379, P78, and P95 show he is not any known subclade of I2b1 so he is, therefore, root/ancestral I2b1*, a.k.a., I-M223* or I-S23*.

Cullen's predictor gives our subject a 100% probability of being I-M223-Cont1.  His haplotype is uncommon.  He has just two 12/12 matches and one near match at 25 markers in the FTDNA database.  At 25 or more markers, his haplotype is unique.
Our subject has opted for deep SNP testing, with these results:
P19+ M170+ M258+ P38+ M223+ P37.2- M161- M26- M21- M227- M253- M307- M72- P30-
The first four positive results prove our subject is Haplogroup I.  The fifth positive result proves he is I2b1.  The first three negative results confirm that he is not any form of I2a.  The remaining six negative results confirm that he is not any form of I1.

#64043 has a rare haplotype, with no matches at any level in the FTDNA database and only some low level matches at Ysearch and SMGF.  His lack of matches appears to stem from unusual values in Markers 393 and 389i (green table cells).  Cullen's predictor gives him a 100% probability of being I-M223-Continental-1.
Our subject has opted for deep SNP testing, with these results:
P19+ M170+ M258+ P38+ M223+ P37.2- M161- M26- M21- M227- M253-  M307- M72- P30-
The first four positive results prove our subject is Haplogroup I.  The fifth positive result proves he is I2b1.  The first three negative redundantly support that he is not I2a.  The remaining six negative results redundantly support that he is not any form of I1.
UPDATE:  Our subject has taken the I2b test bundle at EthnoAncestry, with these results:
S23+ S24+ M223+ M284- M379- P78- P95-
The positive result for S23+ proves he is I2b; the positive results for S24 and M233 prove he is I2b1.  The negative results for M284, M379, P78, and P95 show he is not any known subclade of I2b1 so he is, therefore, root/ancestral I2b1*, a.k.a., I-M223* or I-S23*.
According to Ken Nordtvedt, DYS572=10 is a defining marker for
a cluster within Continental-1, which also contains an Icelander.

Cullen's predictor gives a 78% probability that our subject is I-M223-Cont2a.  Despite that fact, he has only a handful of matches at 12 markers and only one near match at 25.  At 25 or more makers, his haplotype remains unique.
Our subject has opted for deep SNP testing, with these results:
P19+ M170+ M258+ P38+ M223+ P37.2- M161- M26- M21- M227- M253-  M307- M72- P30-
The first four positive results prove our subject is Haplogroup I.  The fifth positive result proves he is I2b1.  The first three negative results confirm that he is not any form of I2a.  The remaining six negative results confirm that he is not any form of I1.

What constitutes a match?
Matches in other surnames are usually mere coincidence, so please ignore them — I'll let you know when you shouldn't!
For 12 markers:  9 or less is a non-relative; 10-12, please see this Chart compiled by FTDNA.
For 25 markers:  21 or less is a non-relative; 22-25, please see this Chart compiled by FTDNA.
For 37 markers:  31 or less is a non-relative; 32-37, please see this Chart compiled by FTDNA.
For 67 markers:  55 or less is a non-relative; 56-67, please see this Chart compiled by FTDNA.
For any test:  0 matching markers, please contact NASA.
