This is becoming an important part of our shared wiki family tree. What we're doing:
This enables members to discover when they could benefit by comparing test results.
It doesn't just benefit those who have already taken tests. It illuminates when taking test would be beneficial, who should take it, and which test they should take.
For an excellent introduction to WikiTree from the perspective of a genetic genealogist, see this November 4 post on Roberta Estes' DNAeXplained blog: WikiTree and DNA.
WikiTree is not collecting raw DNA test information. However, there are always privacy considerations.
We display the fact that a test has been taken. Members have the "DNA Tested" badge and the test lists are public. This is regardless of Privacy Level.
Moreover, we display the fact that a member has taken a test on their family members' profiles. See the Test Connections section below.
The public display of the connection on the family member's profile depends on the family member's Privacy Level. If the family member is Private with a Public Biography or lower, only those on the Trusted List see the connection. If the profile is Private with a Public Family Tree or higher, everyone is able to see the connection.
For example, the fact that Chris Whitten has taken an mtDNA test is linked from his profile. The test connection is not shown on his mother's profile because her profile is private. The test connection on his mother's mother's profile is public because her profile is Private with a Public Family Tree.
We also display the list of test connections made through a particular test if the tested member is Private with a Public Family Tree or higher.
There are additional considerations related to the optional test information you can enter. For example, you can include your ID at the testing company or a matching service such as Ysearch, Mitosearch, and GEDMatch.
Even though your profile at that other website may be public, it may or may not be connected with your real name or personally-identifiable information. Linking it to your WikiTree account will add to what's publicly available.
Finally, there are additional considerations when Entering a Test for Someone Else.
When a WikiTree member has taken a DNA test we report this on some of their family members' profiles.
The method we use to decide which profiles to connect depends on the type of DNA test. See the three types below.
These connections are not made in real-time. That is, when a member says that they have taken a DNA test, the connections do not immediately appear on their family members' profiles.
We update the connections once a day. This means it could take up to 24 hours for connections to appear or change. If you change your family tree, it could be the next day before you see the DNA information on the profiles updated accordingly.
For example, let's say that on Monday, Chris Whitten enters that he has taken a yDNA test. On Tuesday it will be reported on Whitten-56 and other Whitten profiles. If on Wednesday, after comparing DNA test results with Whitten cousins, Chris edits his family tree and is no longer connected to Whitten-56, the notation on Whitten-56 will be removed on Thursday.
If a male WikiTree member has taken a Y-chromosome DNA test we go up the male line, father-to-father, to find the member's earliest-known paternal grandfather. This is the same as what you see on the member's DNA ancestors view.
Then, starting with this earliest-known paternal grandfather, we go down the various direct male lines. The system includes all sons and skips all daughters and profiles without a specified gender. This is the same as what you see on the most-distant paternal grandfather's Y-chromosome descendants view.
If a WikiTree member (male or female) has taken a mitochondrial DNA test we will go up the direct female line, mother-to-mother, to find the member's earliest-known maternal grandmother. This is the same as what you see on the member's DNA ancestors view.
We then include all the children, male and female, of this earliest-known direct-line maternal grandmother.
Then we take the daughters gathered in the previous step and add all her children, male and female.
We repeat this down through the generations. In every generation, all children are included, but only the children of daughters are included in the next generation. This is the same as what you see on the earliest-known maternal grandmother's mitochondrial descendants view.
When a member has taken an autosomal test we use a "six degrees of separation" system. Starting from the member, we follow five steps of blood relationships in every direction.
Our form lets you select from a limited list of tests. Here is the list along with links to which members have taken them:
Have you taken a test that you don't see here? We do want to include all tests from all companies that enable genealogical matching. However, some tests and some companies offer DNA information on ancestry, but not matching for genealogy. This includes:
This information may be wrong or outdated. Please post in G2G with the tag "DNA" if you have new information.
If you plan to order a test for yourself, or would like to recommend that a family member or friend be tested, please use one of these URLs. This way WikiTree gets the referral credit.
You can indicate that someone else has taken a DNA test if you have access to their DNA test information.
Click the "DNA" button near the top of their profile and follow the link from there. You will need to be on the person's Trusted List to do this.
Surname project leaders may have access to kit information for people they don't personally know. These tests can be added to WikiTree but it must be done carefully in order to protect privacy.
Here is a recommended method:
If the test-taker ever wants to participate on WikiTree add their e-mail address to their profile so they can take possession of it. They can then decide how much personal information they want to add and share.
Note: These recommendations are still experimental. Thank you to Kitty Smith for helping in the development.
