All Australians and New Zealanders with the surname Brereton, unless adopted,  originally came from Cheshire or Staffordshire, England. 
 There is a very good chance that the Staffordshire Breretons were originally  from Cheshire.
 Hopefully DNA should soon confirm that assumption.

DNA has shown that the large contingent of Irish Brereton's originally came  from Cheshire.

So far there are 5 separate Brereton trees. Two more tests are pending. These are Y-DNA tests taken by men.
 There is another kind of test called a family finder test that can be taken by either sex. This matches  you up to 4th cousins on either side of your family tree. There are a few Brereton women and men who  have taken this test.

I have two other Brereton sites:
 www.cheshirebreretons.tribalpages.com
 www.irishbreretons.tribalpages.com.

Several of the trees on those sites have descendants in Australia who trace  back to the 1900/2000 century but cannot get any further back. I thought it may be helpful to start an Australian site.

I am only going to put the most basic trees from those that I already have onto this site to start the process. My hope is that others interested in Brereton family history will add to this site.

Once you hit a brick wall with your paper trail DNA testing is the only way to  connect to other trees.
 There is a Brereton DNA group at www.familytreedna.com.

If you are an antipodean Brereton who would like to have your tree on this site  then ask for an invitation. This site is being set up to be collaborative.
