Brown/Browne/Braun DNA Study: Marker Values for Group No. 20     
   
Click here for other Groups    
   
The members of each relationship group below (Groups No. 20 through No. 29) are likely as a rule to share common Brown ancestors with fellow group members inside a "genealogical" time frame, that is, approximately since the widespread introduction of surnames in western Europe during the 15th century.  
   
   
These groupings are strictly tentative, however, and they will necessarily be revised from time to time. What's more, the identification of specific common ancestors for any group will generally depend more upon conventional "paper" genealogy than upon additional DNA testing.    
   
   
To the extent that there are mistakes in the groupings, we have tried to err on the side of inclusiveness by using selection criteria broader than those employed by many other surname-tracing projects. In technical terms, we view a false negative as worse than a false positive, so we prefer to err toward the latter. One implication is that some of this project's Groups will almost surely lose members -- or even "break down" -- if all their members should eventually upgrade from 12 to 25 or more markers. Such outcomes are most probable for Groups equal or close to the so-called "Atlantic Modal Haplotype" (AMH), as for example Group Nos. 5, 15, 18, 20, 56, 59, 87, 88 and 89. For more information on the AMH issue, see the discussion under Group No. 20.    
   
   
 
 
       
Criteria for Determining Relationship Groups:        
   
For Haplogroup R1b and its subclades: Members must match 12/12 on the first 12 markers, at least 23/25 on the first 25 markers, or at least 33/37 on the first 37 markers.  
     
For all other Haplogroups: Members must match at least 11/12 on the first 12 markers, at least 22/25 on the first 25 markers, or at least 33/37 on the first 37 markers.  
   
   
     
Note on Modal Values within Groups: In cases where a specific marker's modal value is undefined, a value is substituted from among the modal values for all project members with the same haplogroup.    
   
     
   
Color coding for Haplogroups:    
   
Green = haplogroup proven by independent SNP test                                  
Red = haplogroup inferred from STR's with high confidence (no SNP test)        
Blue = haplogroup inferred from STR's with medium to low confidence (no SNP test)    
Black = haplogroup presented with unknown confidence (SNP status not known)

Note 1: The members of Group No. 20 above have a DNA signature often called the "Atlantic Modal Haplotype"  (or AMH).  This signature is the most frequent Y-chromosome DNA pattern for men whose roots are in western Europe, above all in the British Isles.  As such, this set of marker values is especially prone to generate "false positive" matches.  An important outcome is that the men in this project's Group No. 20 are less likely than the men in our non-AMH groups to be related to one another within a "genealogical"  time frame, that is, since about 1400 A. D.  In particular,  men at (or close to) the AMH seldom can rely on the results of a 12-marker DNA match for evidence of a genealogically significant relationship.  In fact, even perfect 25-marker matches for men in the AMH category sometimes break down upon an upgrade to 37 markers. The same may be said for men within one step of the AMH, like those in our Groups No. 5, 15, 18, and 59.  Nonetheless,  for all such groups that are close or equal to the AMH, we have included men tested only for 12 markers -- rather than run the risk of missing a relationship that might eventually turn out to be significant.      
 
 
 
 
 
 
 
 
         
Note 2: To understand an important difficulty in interpreting the results for Group 20 and several other groups in this project, especially groups close to the AMH, consider that some members of Group 20, for example nos. 2342 and 68374, don't appear closely related to one another thanks to their divergent results on markers 13 through 37. Yet either man could plausibly be related to any of the men for whom we have results only for 12 or 25 markers. In fact, if any of these men should upgrade to 37 markers, the upgraded results might even form a "bridge" between two men who appear now not to match. Therefore, rather than risk overlooking such potential relationships, we have constituted groups like No. 20 so as to "err on the side of inclusiveness."   For more information on the Atlantic Modal Haplotype, please click here:

***  Indicates "null" or no result. Such cases are retested multiple times to confirm. The underlying science is still unsettled as to when these readings are caused by true deletions, as opposed to being caused by imperfect testing techniques. Regardless of cause, however, mutations that lead to null readings are normally passed to descendants just as are other mutations, meaning that related male lineages such as a father and his son will usually share a null value. Therefore a null value can generally be as useful as any other value for genealogical purposes.
