About us

The Carpenter Cousins Project is a global One Name Study. The primary surname in the project is Carpenter with the variants Carpender, Carpentier, and Charpentier.
To account for immigrants to North America, who may have anglicized their surnames, the project also includes the surnames Cymerman, Sherbondy, Zimmer, Zimmerman, Zimmermann.  For example, Zimmerman(n) is old German for worker of wood, and in North American, on occasion, the surname was changed to Carpenter.

The Carpenter Cousins Y-DNA Project,
an independent public surname project, is focused on the male Y-Chromosome. It was started in 2002. 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. The Carpenter Cousins Project started as the Carpenter CD Project in 1997. 

''All'' biological male Carpenter/Zimmerman Cousins are invited to submit a join request. This project is open to all Carpenter Cousins globally.
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:

The volunteer administrators of the Carpenter Cousins Y-DNA Project includes a member of ISOGG, the Guild of One Name Studies, and also follows the ISOGG Project Administrator Guidelines.

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.
