Burgar

The Table gives the country of origin and the person that provided the test sample. The remaining columns, e.g. DYS 388, are the names given to the markers and refers to the position of this small fragment in the original DNA chain.

Normally, if 23 out of the 25 markers agree, and you have the same surname, then you should be related.

The results of the English Burgar family show that Bill Burgar (born 1937) and Andrew Burgar (b 1963) are related. We differ only on one marker, DYS No. 393. Andrew has a value of 13 (typical of about 80% of Europeans) but Bill has a value of 12, (as in 12% of Europeans). This suggests that one of Bill’s ancestors has undergone this genetic mutation since about 1700, when Andrew’s branch and Bill’s branch of the Burgar family split.

Andrew Burgar and Jack Burgess differ by one marker (DYS No 439). This is the only difference between Andrew and Jack (i.e. a 24/25 marker agreement) so they seem to be positively related. Bill has a two marker difference with Jack, but since Bill is related to Andrew (see below), then Bill Burgar and Jack Burgess are also related.

Andrew and Bill have a value of 14 (typical of only 2% of the European population) whereas Jack Burgess and Bertie have a value of 13 (typical of only 12 % of the European population). Both these values are rare and it must be assumed that the values of Andrew and Bill changed from 13 to 14 in a common ancestor. This might have been John Burgar (born about 1742 and living in London) or an ancestor of his.

Bertie Burgess has 2 markers different from Jack Burgess and is therefore related to him. Like Bill, Bertie’s part of the family would have undergone two changes of marker. It is not possible to say when this happened. Since Jack is the most related to Bill and Andrew and also to Bertie, it is assumed that he has undergone the fewest mutations.

I have searched some DNA database sites with about 20,000 samples to see if others persons have similar signatures.

I have found that when comparing the first 12 markers against Jack’s data that:

6 other persons have the same signature. About 100 persons have the same signature except for one marker. This shows that on the basis of the first 12 markers the Burgess/Burgar are not unusual and have typically Celtic genes.

However, on the last 13 markers of the 25 (which we all have in common) there are only 6 persons who are within 2 markers different. These 6 persons are markedly different on the first 12 markers. The result is that Jack has only a few people that are within 5 markers of his signature when the 25 markers are considered. Andrew, Bertie and Bill who have had some rare mutations have even less relationship to other people.

The Shetland and English branch of the family thus seem to be a distinct family unit.

The most likely scenario regarding the stage of the mutations are shown in the following diagram.

Bertie could have mutated before Bill and Andrew (Bertie 1) or after Bill and Andrew mutated (possibility Bertie 2).

Having established that the English Burgar family came from Shetland, we have next to find the origins of the Burgar family in Shetland.
