The tests shown below analysed 10 markers on the Y-chromosome. The first column in 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.

The sequence of numbers e.g. 14,12,24,11,13,13,10,16,12,12 is referred to as a ‘DNA signature’.
To have any chance of being related, two persons should have 10/10 or 9/10 markers in common.
The Shetland Burgess family and the English Burgar family could be related. This DNA signature is typically Celtic as will be explained later.
The Shetland Burgess and English Burgar families have a very different DNA signature to the Orkney and Canadian Burgar families, and are thus not related to them.
The Orkney and Canadian Burgar families are also unrelated, having only 7/10 markers in agreement. However, their DNA signature is of Norse Viking origin, as will be explained later.
Unfortunately, the above results do not prove that the Shetland and English Burgar families are related. There are databases showing the DNA signature of about 20,000 persons. About 100 unrelated persons in these databases have a similar DNA signature to Jack Burgess and Andrew Burgar.
Since the 10 marker test is not conclusive, the 25 marker test was carried out to positively determine whether the Shetland Burgess and English Burgar families were related.
