Friday Family History: Ancestry's DNA Test

Recently, Ancestry.com launched a new DNA test. It covers the entire genome, and it is equally useful for women as well as men.  One of the very cool features of this test is its ability to accurately tell ethnic background.  Not only does this provide great family history clues, but it can be tremendously helpful for individuals who don't know much about their biological roots.  Regardless of how much information an individual chooses to share with others, it can be unsettling to not know the answer to a question that pops up everywhere:

from the 2010 US Federal Census Questionnaire

Someone I know, who has requested anonymity, but who agreed to share her experience, completed the test.  Once ordered, the test arrived via mail fairly quickly, and just required a small saliva sample.  After mailing it back, the wait began.  The Ancestry website says the results take six to eight weeks, but her results came in just one month. 

Results were fairly accurate and specific.  Not only did she learn which continents her ancestors came from, she now knows percentages and specific regions of the continents.  She previously knew precisely one part of her background, and the test agreed spot-on with that percentage, so she assumes the other results are equally as accurate.  Although a portion of her background came back as "uncertain," that could change as scientists discover more genetic markers. 

Another feature of the results is the AncestryDNA Member Match, which let her know of possible relatives who have also taken the test.  Her results show, with a 95% confidence level, a few individuals who are most likely her 4th cousins.  By comparing family trees, she might be able to discover the connection and learn new information about her ancestors.

Hearing her satisfaction with the test makes me consider ordering one myself.  What about you?  Would you consider taking a DNA test?


 Thanks for amazing technological advances that provide family history break-throughs.

  1. Hi Kristi,
    You're right that this test does have huge potential. However, your friend should not assume that the current percentages of ancestral origins are 100% accurate for now. This tool is still in beta and will continue to change and improve over time. I wrote about this aspect of the test in my latest blog post: http://www.yourgeneticgenealogist.com/2012/06/my-review-of-ancestrydnas-admixture.html

Ten Things of Thankful: Post-Thanksgiving Edition

Hope you had a nice Thanksgiving. I'll jump right in:

1. I'm thankful for cooperative return policies. Several weeks ago, I mentioned that I had to return a range that I had purchased, and I hoped that the particular range was just a lemon and that the replacement wouldn't have the same problem. Well, unfortunately, it did. On the bright side, the store quickly picked up the second range and refunded my money. I'm putting appliance purchases on the back burner (!) for the moment. 

2. I'm thankful for temples. I went one morning this week to the temple. I'm always amazed at how much insight comes in just an hour or two of reflection. 

3. I'm thankful for my sister. She and her family came to Utah to spend Thanksgiving with her in-laws, and I got a chance to see her and her family on Wednesday. The last time I saw her was in January at our grandma's 100th birthday celebration. We feel lucky to have two visits in one year! 

4. I'm thankful for my brother. …

Ten Things of Thankful: California Poppies

Spring has arrived.  On Wednesday, I took off for a few hours to hike.  The weather was perfect:  the sun was shining, the wind kept itself to a cool, slight breeze (as opposed to Thursday, when the sustained wind speed was 37.5 mph), and the temperature was warm, but not oppressive.  

My Ten Things of Thankful list this week will be mostly made of photos.  Each time I climbed another hill, or turned another corner, I was delighted with the new view.  Come along with me!

The poppy fields can be seen from miles away.

Many other people had the same idea I had on Wednesday. The line to get into the Antelope Valley Poppy Reserve was longer than I've ever seen it. Many cars turned around and decided to just park on the main street and hike into the reserve.

Once I finally got the car parked and started to hike, I was greeted with wonderful views.  I hiked the steepest and furthest trails, and was rewarded by moments of solitude.
