Haplogroup G is relatively uncommon in European males (about 2% of the population).  It is believed to have originated in Central Asia, then to have spread to the Middle East and then to have become widespread in Europe during the Neolithic.  The most common subclade among Europeans is G2a, which is found at low frequency among Scandinavians. 

There is a set of G2a modal haplotypes in the Ysearch database (viz., TQYVN, RT3G7, U2WBK, 7HV7Q, HYQVS, YWIHN, and FXYWN) uploaded by Carl-Johan Swärdenheim, founder of the Scandinavian Y-DNA Project at FTDNA.  One of them (viz., TQYVN) is a 16-marker haplotype called the "Security" haplotype because it is intended to be used for deducing Haplogroup G2a when no SNP test has been done.  If someone has a genetic distance greater then 3 from the G2a Security haplotype, it is very unlikely that they are Haplogroup G2a.  The other six G2a haplotypes at Ysearch are modal for various geographical regions, namely:  central European, southern European, southern Britannic, eastern Britannic, Arabian (Al Quraishi), and Indian (Brahmin).
Five members of Danish Demes are Haplogroup G, plus one individual tested outside the project.

This individual has a rare haplotype with no matches (or even near matches) at any level in either the FTDNA or Ysearch databases (at least as of Aug 2008).  A backbone SNP test (M201+) proves he is Haplogroup G; he is deduced to be G-2a based on his haplotype.

These individuals have a rare haplotype.  Except for one 24/25 match in another surname, their only matches in the FTDNA database are with each other.
#N54795 has been deep SNP tested with these results:
P15+ P303+
The positive result for P15 proves he is G-2a; the positive result for P303 proves he is G-2a3b-1.

This individual has a few dozen 12/12 matches and a handful of 23/25 matches in the FTDNA database, but he has no near or full matches at 37 (or 67) markers at FTDNA or Ysearch.  His social surname is MacLAUGHLAN, but he is biologically a PETERSEN.
Our subject has been deep SNP tested with these results:
M201+ P15+ P303+ P16- M286- M406-
The positive test for M201 proves he is Haplogroup G; the positive test for P15 proves he is G-2a, and the positive test for P303 proves he is G-2a3b-1.  The negative test for P16 proves he is not G-2a1, the negative test for M286 proves he is not G-2a2, and the negative test for M406 proves he is not G-2a3a.
   
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.
