Clan Y-DNA Results

A value of “0” for any marker indicates that the lab reported a null value or no result for this marker. All cases of this nature are retested multiple times by the lab to confirm their accuracy. Mutations causing null values are infrequent, but are passed on to offspring just like other mutations, so related male lineages such as a father and son would likely share any null values.

It is obvious from our observation of 10's of 1000's of samples that some markers change or mutate at a faster rate than others. Therefore not all markers should be treated the same for evaluation purposes.

The markers in red have shown a faster mutation rate then the average, and therefore these markers are very helpful at splitting lineages into sub sets, or branches, within your family tree.

Explained another way, if you match exactly on all of the markers except for one or a few of the markers we have determined mutate more quickly, then despite the mutation this mismatch only slightly decreases the probability of two people in your surname group who match 11/12 or even 23/25 of not sharing a recent common ancestor.

Haplogroup R1b:

The founder of the R1b lineage lived over 35,000 years ago prior to the end of the last Ice Age in southern Europe and Iberia. Members of Haplogroup R1b are believed to be descendants of Cro-Magnon people, the first modern humans to enter Europe. Cro-Magnons lived from about 35,000 to 10,000 years ago in the Upper Paleolithis period of the Pleistocene.

When the ice sheets retracted at the end of the ice age, descendents of the R1b lineage migrated throughout western Europe. Today, Haplogroup R1b is found predominantly in western Europe, including England, Ireland, and parts of Spain and Portugal. It is especially concentrated in the west of Ireland where it can approach 100% of the population.

This haplogroup contains the well known Atlantic Modal STR Haplotype (AMH). AMH is the most frequently occurring haplotype amongst human males with an Atlantic European ancestry. It is also the haplotype of Niall of the Nine Hostages, an Irish King in the Dark Ages who is the common ancestor of many people of Irish patrilineal descent.
