Can AncestryDNA Find Siblings?


It can be very daunting to try to find a long-lost sibling. That’s because it usually entails putting on a detective hat and combing the entire city and at times even the whole planet. So read on if you are thinking about embarking on a journey to locate a brother or sister (or even a half-sibling) — I will tell you how you can find him or her without putting too much effort into it.

Can AncestryDNA find siblings? Yes, it is possible for you to be able to locate a sibling by means of genealogy or an ancestry website such as AncestryDNA. It also allows you to find other blood relatives like aunts and cousins, not just siblings.

While it’s true that finding a sibling is easier now more than ever (thanks to the internet!), there are certain factors that can get in the way of you trying to find a brother or sister you always knew or felt in your gut you have. For instance, for best results, you and the sibling you are looking for should have taken DNA tests with AncestryDNA or any other similar service provider. The good news is that finding him or her is still very much possible even if it’s a close relative of his or hers who has taken a DNA test.

Finding a Family Member Can be Life-Changing

DNA testing came into being not too long ago — 1986, to be exact. It was developed initially for cracking unsolved crimes by matching genetic materials found at crime scenes to the DNA of suspected individuals. Eventually, getting one’s DNA obtained and analyzed had a bunch of other uses, such as for paternity testing and piecing together a family tree.

There’s something about finding a blood relative like a sibling that’s life- and game-changing. Knowing that someone else you’ve never met before has also developed and grown for nine long months in the very same uterus where your existence began can be very exciting and at the same time overwhelming.

Or perhaps you feel that you don’t belong to the family of which you’re a part — having no one that looks and acts like you can certainly leave you feeling alone and unneeded.

Maybe when you were just a child you’ve always heard from someone that you have a sibling who’s being fostered by another family from another state or country, and now that you are an adult and have all the power and capacity to find him or her you simply can’t because you have not one piece of information that you could use for the search.

Various reasons exist why one would like to learn about a sibling, even a half-sister or brother, and ultimately make that connection. But no matter what it is, locating that person is practically trouble-free with the help of genealogy or an ancestry website!

Using the Website is the First Step to Take

Just like any undertaking on the face of the planet, your search for a person whose genetics is very much similar to yours begins with a single step. In this day and age, that initial step could be something as simple as logging on the web and visiting AncestryDNA.

If you have never heard or read about AncestryDNA before, here’s a quick look at it: AncestryDNA is just one of the many sites on the web visited by individuals who would like to learn more about their roots. The website and the service it provides work by analyzing your DNA, which they can obtain by sending you a vial that you will have to fill with your saliva, which you will have to ship back to them afterward.

AncestryDNA and other similar service providers in cyberspace (some very common examples are 23andME.com, FamilyTreeDNA.com, and Ancestry.com) are extremely popular these days.

At the onset of 2019, it is said that more than 26 million people have used these sites for fun or any other reason — that’s a lot of spit jetting from homes to DNA testing companies!

Once AncestryDNA or any other site of your preference has received your saliva, it will begin to analyze it, which can take anywhere from 3 to 8 long weeks.

What’s so nice about AncestryDNA is that it will provide you with results consisting of 3 parts: an ethnicity estimate, your DNA matches, and the company’s very own ThruLines which is something that tells you which people match your DNA and how they could be related to you.

Ranking Based on How Much DNA Material is Shared

While waiting for AncestryDNA to release the results of your test, use your time wisely by filling out your genealogy chart — someone somewhere could in fact be looking for you or your relatives, and that is why documenting your very own biological family is a good idea.

The moment that you have obtained the results, you can start attaching those who match your DNA to your family tree in order to complete the picture.

Speaking of which, AncestryDNA will provide you with matches following a ranking system in which those who share with you more DNA are given high ranking as you have a closer relationship with each other. Relationship types according to ranking are parent or child, immediate family members, close family members, 1st cousin, 2nd cousin, 3rd cousin, and so on.

As a general rule of thumb, you should begin piecing your family tree together by clicking on the names of your closest matches so that you may be able to learn more about them.

Looking at their respective family trees allows you to come across individuals. Every green leaf is a person commonly shared. If the tree is gray, unfortunately, it is set to private — you could politely ask the individual if it’s okay for you to take a look at it.

There are Certain Things That Could Get in Your Way

It’s true that you can breathe a sigh of relief once your DNA test results have been released to you by AncestryDNA — first step done!

However, the hunt for your long-lost brother or sister does not end there. That’s because you will also have to devote some of your time and energy to contact your matches, be it your sibling or other blood relatives who could help bring you to the person you are looking for exactly.

Getting in touch with your matches, needless to say, can be both exciting and nerve-racking as no one can really tell how they will react to your message. Yes, AncestryDNA, as well as most other genealogy or ancestry sites, make it possible for consumers to send messages to one another.

As a general rule of thumb, one should practice caution and also be sensitive in order to keep the message’s recipient from feeling terrified, alarmed, or even being scammed.

Before I forget, when looking for your sibling online via DNA testing it’s a good idea to choose a website whose DNA database is impressively sizable — go for one that millions of consumers are opting for.

That’s because this will considerably increase your likelihood of finding your sibling or other relatives. There’s no need for your brother or sister to have used the same site — having some of his or her relatives using it is oftentimes more than enough to ensure your success.
