DNA Circles at AncestryDNA can get problematic when participants’ trees are unverified. This is why.
Adding people to a family tree without verifying the connection is a fairly common genealogical practice. This happens a lot when people “graft” information from another online tree.
In addition to the problems this can create in your tree, it can create problems when you start looking at genetic connections. We have received a few inquiries about this topic here at Genealogy Gems, and I chatted with a fellow genealogist about this at a recent conference.
The practice of copying online trees factors most heavily in the DNA Circles and New Ancestor Discoveries (NAD) at AncestryDNA. You will remember from our previous conversations that these tools are like parties that your DNA has secured your tickets to attend. Each of these parties is “hosted” by one of your ancestors, in the case of the DNA circle, and a presumed ancestor, in the case of a NAD. Sometimes we catch ourselves declaring that our membership in the DNA circle “proves” our connection to the party host.
But we must be careful. Because it does not.
“Proves” is too strong of a word. All your membership in the DNA circle can really tell you is that you have a genetic connection to those marked with the orange line. Those with the grey connecting lines have a DNA connection to some of the circle members, but not to you. Placing the name of an ancestor on the cover of this gathering does not guarantee that the named person is your common ancestor. It is just a suggestion; a hint.
Think about this for just a second. Let’s say that Joan does a bit of research and decides that her immigrant ancestor’s father is Marcus Reese, born in 1823 in Wales. She adds this to her pedigree chart. She sees on a census record that he had four children, one of whom shared the name of her ancestor, William, and adds those to her chart as well.
Months later, Charlotte is researching her Mary Reese and sees Mary listed on Joan’s pedigree chart as the child of Marcus. She knows Mary’s father was born in Wales and adds Marcus to her pedigree chart telling herself that she will go back later and double check. And so on.
After a while, we have 7 people all connected back through Marcus and his four children, and they all independently decided to get their DNA tested through Ancestry.com.
Ancestry sees their shared DNA and that they have all listed Marcus Reese as their common ancestor. So they create a DNA circle for the seven of them, with Marcus Reese at the head.
Ancestry did not look at the number of cited sources or the myriad of other genealogical possibilities about how these seven individuals could all be related to each other. It saw a genetic connection and a genealogical hypothesis, and it presented them to you in the form of a DNA circle.
The genetic evidence supports a single common ancestor for these 7 people, but it certainly does not have to be Marcus Reese. You can become more certain as you gather the traditional genealogical evidence that you would in any other case. As your documentation mounts, so will your confidence, with the DNA acting like an invitation to keep searching for further evidence of your connection.

Organize DNA matches with this innovative approach. If you are feeling overwhelmed with your DNA results, you are not alone. Learning to organize your DNA matches in an effective way will not only keep your head from spinning, but will help you hone in on possible matches that will break down brick walls. Here’s the scoop from Your DNA Guide, Diahan Southard.
I can tell whose turn it was to unload the dishwasher by the state of the silverware drawer. If either of the boys have done it (ages 13 and 11,) the forks are haphazardly in a jumble, the spoon stack has overflowed into the knife section, and the measuring spoons are nowhere to be found. If, on the other hand, it was my daughter (age 8,) everything is perfectly in order. Not only are all the forks where they belong, but the small forks and the large forks have been separated into their own piles and the measuring spoons are nestled neatly in size order.
Organize Your Imaginary DNA Drawer
Regardless of the state of your own silverware drawer, it is clear that most of us need some sort of direction to effective organize DNA matches. It entails more than just lining them up into nice categories like Mom’s side vs. Dad’s side, or known connections vs. unknown connections. To organize DNA matches, you really need to make a plan for their use. Good organization for your test results can help you reveal or refine your genealogical goals and help determine your next steps.
Step 1: Download your raw data. The very first step is to download your raw data from your testing company and store it somewhere on your own computer. See these instructions on my website if you need help.
Step 2:Identify and organize DNA matches. Now, we can get to the match list. One common situation for those of you who have several generations of ancestors in the United States, is that you may have ancestors that seem to have produced a lot of descendants. These descendants may have caught the DNA testing vision and this can be like your overflowing spoon stack! All these matches may be obscuring some valuable matches. Identifying and putting those known matches in their proper context can help you identify the valuable matches that may lead to clues about the descendant lines of your known ancestral couple.
In my Organizing Your DNA Matches quick sheet, I outline a process for identifying and drawing out the genetic and genealogical relationships of these known connections. Then, it is easier to verify your genetic connection is aligned with your genealogy paper trail and spot areas that might need more research.
This same idea of plotting the relationships of your matches to each other can also be employed as you are looking to break down brick walls in your family tree, or even in cases of adoption. The key to identifying unknowns is determining the relationships of your matches to each other.
Step 3: See the relationship between genetics, surnames, and locations. Another helpful tool is a trick I learned from our very own Lisa Louise Cooke–that is Google Earth. Have you ever tried to use Google Earth to help you in your genetic genealogy? Remember, the common ancestor between you and your match has three things that connect you to them: their genetics, surnames, and locations. We know the genetics is working because they show up on your match list. But often times you cannot see a shared surname among your matches. By plotting their locations in the free Google Earth, kind of like separating the big forks from the little forks, you might be able to recognize a shared location that would identify which line you should investigate for a shared connection.
So, what are you waiting for? Line up those spoons and separate the big forks from the little forks! Your organizing efforts may just reveal a family of measuring spoons, all lined up and waiting to be added to your family history.
“Proves” is too strong of a word. All your membership in the DNA circle can really tell you is that you have a genetic connection to those marked with the orange line.
