BARNARD/BERNARD (and variations)

Surname Project Results

The table below illustrates the marker results for the BARNARD/BERNARD DNA (and variants) Surname Project.

There are some simple rules of thumb for considering participants to be related through a common ancestor:

At 23 markers; 21/23, 22/23 and 23/23 matches
At 33 markers; 30/33, 31/33, 32/33 and 33/33 matches
At 43 markers; 39/43, 40/43, 41/43, 42/43 and 43/43 matches

It is risky to place too much emphasis on the time scales of when the most recent common ancestor actually lived based upon statistics. To do so provides false accuracy to the interpretation due to very large error margins in the statistical calculations. The paper and oral records are a far better guide where available.

When you do find many differences between presumed cousins which, according to the rules above, is on the boundary of relatedness (e.g., a 39/43 match), a 'bridge haplotype' can often be found. This is an individual with a haplotype in between the two cousins (e.g., a 41/43 match) that shares one or more of the mutations, thus connecting the cousins. This 'bridge' can only be found by testing other cousins but is often beneficial in strengthening the evidence that all of the cousins are indeed related, simply on different branches of the same family.

The green, pink, and yellow columns indicate a likely relationship between those sharing the same background colour.  The white background columns contain those participants who have not yet found links. An 'x' in a cell indicates there is no result known for that marker.

Earliest Known Ancestors of Participants                

The following table is added on the understanding that these ancestors are verified by the participants only and not by the group administrator. Any perceived discrepancies should be taken up with the participant concerned.
