There is a sister project, the 'Atkinson & variant', study, namely: The Atkins/Adkins Study.
I'm discussing the study here in that it has been noted that there is some crossover between the studies ie individuals in which the surname spelling 'Atkinson', & 'Atkins' (or variant) may interchange. As a living Atkinson I find that frequently happens to myself, individuals not hearing the last syllable and writing my name incorrectly. The Atkins/Adkins Study has to-date 30 members. The results for which can be seen at: www.familytreedna.com/public/adkins
The following links will take you to a comparative tables between the two studies. Before looking at these tables I should point out a number of factors that need taking into account:
1) Testing has taken place across different companies. Different companies test different markers. Thus although the following tables may indicate that participants have tested say 37 markers comparison marker to marker may not be completely possible. For example, an individual testing 37 markers with FTDNA may only be able to compare 32 of their markers with an individual who has tested with relative Genetics.
2) Also of note because we are comparing markers tested by two different companies this involves adjusting some of the marker numbers. Namely, GATA H4. I've added 1 to FTDNA results for accurate comparison to the SMGF results.
3) Some individuals tested with FTDNA have been found to have a null value at DYS 439. This has a particular importance. To understand this see: http://www.familytreedna.=Null
NB: for simplicity I've only included those results from the Atkins/Adkins study which have a clear connection to each other and those from the Atkinson study which clearly may indicate a crossover:

Looking at the genetic distances in the above tables would indicate:
There would appear to be several possible connections with some members of the Atkinson group and those of Adkins/Atkins. Many of these are however based on only 12 marker comparisons and as such should be viewed with caution. 12 markers are only really of use for very rare surnames and of little use for common surnames such as Atkins or Atkinson. I have many examples on people apparently matching on 12 markers but the match disappearing when the numbers of markers are upgraded. Conversely I have exact opposite examples of people not appearing to match on 12 markers but having upgraded find a clear, though distant, connection. Therefore excluding the 12 marker matches there are the following Atkinson - Atkins connections:
At first glance Robert Atkinson is a 19/21 match with Joshua, David & Kyle Atkins. They however have a NULL marker. We don't know if Robert has such a Null marker as he tested with a different company (RG) and I am informed that their test does not pick up this.
Of more interest:
James Atkisson is a 26/26 match. A genetic distance of 0 from Marion Douglas Atkins family (they have tested via the same company). The conclusion of this is a 50% probability of a connection within 3 generations. The 95% probability is of a connection within 12 generations. This is very promising for a connection. NB: this is based on FTDNA's mutation rates which are criticized as too optimistic according to Sorenson he has a 75% probability of being connected to them within 16 generations. It would be worth James upgrading the numbers of markers he has tested on for more confirmation. Fred, Gary & George Adkins/Atkins all match James 12:12. They also match Marion Douglas's family 12:12.
4th Aug '06 update yet another connection AF Atkinson (see FTDNA Atkinson study: http://www.worldfamilies.net/surnames/a/atkinson/results.html ) is a 23:25 connection with the grandson of David Franklin Atkin on the sorenson project.
Adkins/Atkin Matches: amongst the Adkins/Atkins group, there are a number of 12/12 matches. These may be proven or disproved connections on upgrading. They really warrant doing so.
A number are kin as indicated by their paper-trails and also backed up by DNA. Notably:
Timothy & Marvin Atkins 34/37 or a 50% probability of a connection within 10 generations..
Joshua to David 34/37, Joshua to Kyle 35/37, David to Kyle 36/37. This is a clear connection between the three of them. Arthur & William both match the three of them on either 11/12 & 12/12 but all 5 of these individuals have a Null Value on DYS 439 further adding to strengthen the argument for a connection.
Gary Atkins has only tested on 12 markers but I note from his paper trail he shares descent from Bartlett Atkins b. 1809 Va., with Marion Douglas Atkins grand son and great great grandson. Notably he matches them a 12/12. He is a 12/12 match with James Atkisson . *postscript: Gary has confirmed for me that indeed he is the grandson of Marion Atkins and that Marion's homestead is still occupied by family. Bartlett was bn in either Va or Ten. and died in Batchtown, Ill. 19 Oct 1865. This family would appear to have links with the Mullins, Sloan & Hall families of Pittsylvania. Their results match closely a group on the Mullins DNA Study: http://www.familytreedna.com/(xyemyb45sgfmfxngkl01d255)/public/Mullins/index.aspx?fixed_columns=on
