The discussion of Table II indicated that the test results have been grouped according to their genetic distance from one another. Table III presents these genetic distances at 25 markers for the reference haplotypes of each group in Table II.
Without some other connection, men with a genetic distance of four or greater are normally not considered genetically related, even though they all have the same Beatty surname (various spellings).
Not many definitive conclusions can be drawn from this table except that the Beatty surname represents a rather genetically diverse group. In some cases, the differences can perhaps be explained by 'non-paternity' events. Or, the differences might suggest that the Beatty surname arose from different, unrelated males in the distant past.
Beyond their value in traditional genealogical research, the differences don't really matter. A Beatty is a Beatty, irrespective of the genetics. There is a kinship among Beattys, regardless of lineage number. Perhaps this feeling of kinship is a vestige of an ancient clannish necessity in Scotland. Who knows? Who cares? We are who we are!
