The ultimate purpose of this page is to discuss our DNA results.
- This project has only recently been started so we only have results from 4 persons so far. (See below). An example of what this page will look like over time is the Hodges DNA Project Discussion Page

2 Aug 2013. We have two members so far: the William Brewerton on our y-Results page matches a Brereton who tested with another company and who we hope will transfer his results to this project. They are both in the very common haplogoup R1b1a2 (R-M269). Also we have a Brereton with a Trinidad/West Indies pedigree who has tested in the FTDNA lab for the National Geographic geno 2 project. That test does not provide Y-STR markers so he has now ordered the YDNA37 test, and should get the results in a month or two. The interesting thing is that his haplogroup is I-L39, which is between 100 and 200 times rarer than R1b1a2 in the British isles. So we already are absolutely certain there are at least two unrelated branches of the Brereton Surname. If other Breretons test and also find I-L39, then because of the rarity it is much more likely you will find that the STR markers will show your families to be related.
25 Aug 2013. We now have results for a new member in the patriarch line"Breretons of Walgherton, Wybunbury and Liverpool". Alyn's line could match the William Brewerton line, an upgrade from 12 to more y-markers has been advised. Sept 2013. Results are now in and some SNP tests are under way.
1 Sep 2013. We now have 12 marker results the from the first test panel for the Brereton Trinidad line (results from the rest of the y-37 panels will follow later). As mentioned above, this line is the rare I2b2 haplogroup, also known as I-L39. 12 Sep 2013. The y-37 results are now in, and there is only a single match showing. It is at 4 steps and to an apparently unconnected surname. If other Breretons who Y test find that they are in this haplogroup, then probablity of a common ancestor will be very high.
7 Nov 2013. We now have results transfered from Ancestry.com for the line of Arthur Brereton c.1791. There is now a group of three project members who have who together appear to be all in the haplogroup R1b1a2 or R-M269 as it is also known. (See the group on the results page labled R1b- lineage I). More tests results have been ordered in order to learn more about the matches in this group of Breretons.
14 Nov - 9 Dec 2013. The SNP test results have come in for William Brereton ( c 1755. Wybunbury, Cheshire) and for William Brewerton (1765-1805 Cheshire/Flintshire). Both are L51+ and P310- , which places them in the rather uncommon haplogroup R1b-L51* (ie R1b1a2a*). which has a frequency of around 0.5% in UK. It begins to look very likely indeed that when further tests have been completed on Arthur Brereton (c1791 ) that he will also be found to match. This close matching is giving rise to reinforced efforts to search in Cheshire for a common Brereton ancestor of this lineage group. Both this lineage group and the I-L39 mentioned above provide two very interesting targets for other Breretons who have not yet undertaken DNA testing to consider. If you were to discover a match you might be led to discover more of your own Brereton lineage.
Participating in a Surname DNA Project provides:
- A report on the participant's genetic DNA, which is very close (and sometimes identical) to the earliest known ancestor
- A classification of the participant's "deep" ancestry, which gives insight into the prehistoric origins of your surname ancestors
- A sense of camaraderie with all who participate in the Family Project, which is particularly strong for those who share a genetic ancestry
- Stimulation to family research and sharing of information
- A wider sense of identity and relationship, as we begin to realize how much we are a World Family.
- A chance to compare your genetic ancestry with those of the Surname and the Variant Spellings
- Locates the genetic matches that do not share your common surname
