About us

February 7, 2020 - UPDATE

The Carpenter Cousins Y-DNA Project is asurname project (Carpenter, Zimmerman and related surnames) with 37 organizedand unique genetic Y-STR groups.  There is one group (98) based on theR-M269 Haplogroup (the most common one in Western Europe) and another ofgeneral no genetic matches found with the project surnames.

We have now some 119 unique geneticprofiles from 444 FTDNA members and some 30 members from other DNA testingcompanies. 

The closest two groups geneticallyrelated are Groups 2 and 3 which have a base genetic distance of 3 at 111markers. In most other surname projects they would be lumped together. Butgenetic genealogy triangulation clearly proves they are two separate geneticgroups. And the documentation found clearly supports this.  While theyhave a common genealogical and genetic ancestor, that person has not beenfound. lineages of members at:

These two groups share the same terminalSNP (single nucleotide polymorphism) of R-YP6281.  This terminal SNP wasdetermined by both Big Y-500 and Big Y-700 testing.  The SNP is defined bythe long hand Haplogroup designation of Ria1a1b1a3c~? (SNP YP6281) – with acreation of about 2,500 years ago.  Using more progressive mathematicalmodeling the estimate is about 1800 ybp.

The SNP matches found have either earlieror later confirmed SNPs with only minimal matching data. This simply means thatthey share an earlier base SNP but not terminal SNPs. Thus they are notdirectly related to Group 2 and 3.  Please see my basic Real Deep Ancestryat: Please note that only one line on that page is related to genealogy. It isthe line beginning with: Me. The rest is anthropology in nature.

Our Group 5 have had the most BigY-Testing and their terminal SNP is I-BY194926. It is a subset of the R-M269line. It is estimated  (progressive modeling) to have been created about1580 AD.  This based on the 90% probability with a likely range of plus orminus 350 years.  While the Group 5 ancestor was born about 1575, it wouldbe irresponsible to even suggest they are one and the same.

In both Groups 2 & 3 and 5, the SNPtesting was not helpful in determining time to the most recent common ancestor(MRCA) compared to what was done via Y-STR testing.  Most SNPs, except forGroup 5, have their terminal SNP tested well beyond the genealogical timeperiod in Europe. The effectiveness of such SNP testing via the Big Y tests arenot reflected in the price nor in results for our genetic genealogyproject. 

Such Big Y testing may be more effectivein geographical types of DNA projects by determining an anthropological commonancestor or Haplogroup using SNP testing. For example, Niall of the NineHostages is a legendary and the “most prolific warrior in Irish history. A teamof geneticists at Trinity College Dublin led by Professor Dan Bradleydiscovered that as many as 3 million men worldwide may be descendants of theIrish warlord, who was the Irish “High King” at Tara, the ancient center ofIreland from A.D. 379 to A.D. 405.”

The SNP testing does provide anthropological, specifically molecular anthropology, data points for comparisonwith most often unnamed human remains. This is usually more appropriate fordeep ancestry and not genealogical studies. For example, very few of thepotential 3 million genetic descendants (based on the Haplotype) will ever seeor have a genealogical record connecting them to the “High King” at Tara. Mostwill be satisfied to say they are a descendant if they have the samehaplotype.  Whether they can “prove” it or not genealogically isimmaterial and clearly anthropologic.

In general, Haplogroups are measured inthousands and tens of thousands of years. Their subsets, often calledHaplotypes can be estimated (plus of minus x years) into the historical timeperiod for the most common types. The best example of such is the R-M269 usingthe shorthand code for the longhand or more formal designation of R1b1a1a2defined by SNP marker M269 and its subsets.

Please remember …

Genetic genealogy is the use of Genealogical DNA tests, i.e. DNA profiling and DNAtesting in combination with traditional genealogical methods, to infer biologicalrelationships between individuals. Genetic genealogy involves the use ofgenealogical DNA testing to determine the level and type of the geneticrelationship between individuals.

Molecular anthropology is a field of anthropology in which molecular analysis is used todetermine evolutionary links between ancient and modern human populations, aswell as between contemporary species.  …

By examining DNA sequences in differentpopulations, scientists can determine the closeness of relationships betweenpopulations (or within populations). Certain similarities in genetic makeup letmolecular anthropologists determine whether or not different groups of peoplebelong to the same haplogroup, and thus if they share a common geographicalorigin. This is significant because it allows anthropologists to trace patternsof migration and settlement, which gives helpful insight as to how contemporarypopulations have formed and progressed over time.



The Carpenter Cousins Y-DNA Project, an independent public surname project, is focused on the male Y-Chromosome. We track Carpenter/Zimmerman and related such names via Y-DNA in this public Y-DNA surname study.  

For this reason we do not track or use mtDNA (mitochondrial DNA) or atDNA (autosomal DNA aka Family Finder) and other DNA tests.  

We need Y-DNA testing for this Y-DNA surname project. For details please go to our Carpenter Cousins Y-DNA Project web page at:

The Carpenter Cousins Y-DNA Project is part of the Carpenter Cousins Project

''All'' biological male Carpenter/Zimmerman Cousins are invited to submit a join request. 
Female Carpenter/Zimmerman Cousins are encouraged to sponsor a biological male Carpenter/Zimmerman relative and to submit a join request. 

The surname ''Carpenter'' is registered with the Guild of One Name Studies. See: - see also:

Effective 25 May 2018 there was major changes at FTDNA due to the European GDPR (General Data Protection Regulation). 

The default setting is Minimal Required which equals NO SHARING either with the Group Administrators or the public. 
You must actively choose to share data (opt in) by changing settings on you FTDNA dashboard to allow the Group Administrator Access (full or partial) and or public access of the Y-DNA results. Those who do not change their default setting effectively makes them a non-member of this project at FTDNA and subject to removal in the future.

"Minimal Required" access effectively makes your Group Administrators (GAs) blind. We do not get notifications of non-group match results, we can not see any Y-DNA results or matches directly and it is as if you are not a member of the Carpenter Cousins project. 

"Minimal Required" access is really no direct access for GAs.
Again, you must sign in to your FTDNA account to change the GAs access level.  

Sign in to FTDNA. Go to the left side of your FTDNA personal results page and look for "Manage Personal Information." Click on that link. Then click on the “Project Preferences” tab. There you will see “Your Projects” that you have joined. On the line with “Carpenter Cousins” you will see the names of the“Group Administrators” listed as “John Chandler, John Carpenter, Terry” Carpenter. 

There you can edit the level of access under the orange Edit tab. There you allow the current and future administrators access to your account information. The level of access recommended for these co-Group Administrators is “Advanced" access but “Limited" access is also acceptable. 

"Minimal Required" access is the default and is the most restrictive and it is not recommended.   

Advanced access allows the Group Administrators to see your FTDNA contact data and update your information as per your requests. Administrators can never change your primary email address but can add any new data or changes as you provide.This is the suggested level.
