Family Tree DNA's 25 marker test points to a much lower number of generations to the most recent common ancestor than other commercially available tests. We use exacting statistics appropriate for the non-independent transfer of genetic material on the Y Chromosome.

· For scientific calculations a Generation is considered to be between 15 and 25 years

A note from Family Tree DNA..........

It is obvious from our observation of 1000's of samples that some markers change or mutate at a faster rate than others. While that actual 'faster rate' has not yet been definitively calculated, 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.

The Stockton DNA Project has identified 5 very distinct Stockton lines todate……….

The Robert Stockton PA/Davis Stockton VA line found to be represented by the Haplogroup ( I) with haplogroups, I1b, J, J2, Q, R1b also within the family linage. These two lines have been confirmed as related threw DNA test results.

The James Stockton New Jersey to Illinois line found to be represented by Haplogroup (R1b) within the family line.

The Richard Stockton England to New Jersey line found to be represented by Haplogroup (G), with haplogroups E1, E3a, I, also within the family lineage.

The William Stockton line from Sutton Green, Isycoed Wales UK. (1710 - 1771) A line Shown to be Haplogroup (G) with a 2 step mutation from The Richard Stockton N.J. family line.

The William Stockton line of Bunbury, Cheshire England (b ? – d. 1789 ) Haplogroup (G) found to be a 1 step mutation from the Richard Stockton of N.J. Family line, a possible match or close relationship of this line
