Do A DNA Test

There are many reasons why a person might not know their biological father, and generally, unless a family member knew the answer and was willing to tell you, you might not ever find out.  Court records are usually sealed, and privacy laws protect vital records; sometimes, paternity secrets die with family members.

Often the paper trail and hospital records with valuable information might be impossible to find. Taking a DNA test to determine your ancestral family lineage will help you find your father easier.  Here we show you how to.

Take an autosomal DNA test

An autosomal DNA test can be taken by males or females and can provide DNA matches up to 5 and 6 generations on both your biological father and mother’s sides of the family.

Test with more than one DNA company

If you test with more than one DNA company, your DNA can be matched to a bigger database of potential family members.

Compare the DNA matches

A DNA match is sometimes referred to as a “cousin match,” which is the result of your DNA data that were compared to other people’s DNA data on file. These matching segments of chromosomes were used to identify and indicate a family relationship. Once your DNA was tested, you will be provided with a DNA match list. 

Review your DNA matches, and even if you do not find a parent match in your match list, you could find a half-sibling match, a close cousin match, or a more distant cousin match. You can still be successful in connecting with your biological family. You might find that some of the DNA cousin matches have additional information available for you. 

Additional information could include family surnames, places of origin, or even a family tree with names, dates, and places.

How to Find a Biological Father That Hasn’t Tested DNA

Many people in the world haven’t taken a DNA test.  These persons won’t show up on databases. Yet, it is still possible to locate your biological father even though he hasn’t taken a DNA test.

We will show you how you could locate your biological father using a combination of your DNA results, family trees, and a little bit of detective work using these techniques.

If a parent hasn’t tested on any DNA database, it is likely, that you will only receive DNA matches from far distant relatives on your test. Don’t be discouraged when your closest match is a cousin who only shares 3% of your DNA. With this information, you could still be able to locate your biological father through them.

Try Googling for Information

If you sent a message through the DNA website and haven’t heard anything in return, you can try looking the person up online.  Most DNA research website users register their DNA kits using their first and last name.  You would be able to see the country where they are located, and you might locate them easily using that information.

Many people who did not receive a response via the online messaging system could find a Facebook profile or a website with contact information.  

If you find your DNA match on a social media platform, be aware that your message might not arrive directly in your DNA match’s inbox due to message filtering privacy settings that prevent spam.

If you do not get a response, you could try adding the DNA match as a friend or commenting on one of their public posts trying to get their attention, explaining that you are trying to reach them about a DNA match.  Ask them how best to contact them or trying to connect through a person who knows them.

Additional Helpful Features

Sometimes, when you are unable to contact a DNA match, you can use these additional features to help with your search:

Family Trees 

MyHeritage at  will allow you when a DNA match has been associated with a family tree, let you view that family tree, and locate the DNA match on it.  You can also view the names of deceased family members on that family tree, and this can provide clues that can lead you to your biological father.

Even without a DNA test, when you have some basic information about your biological father, you can learn more about him by building a family tree on This may lead you to other family trees built by relatives of your biological father, who you could then contact for information on your biological father.


Some searchers have found the ethnicity results helpful when searching for a biological parent, especially if the parents were of two distinct ethnicities. Learning about your ethnicities could give insight into your biological parents’ location and help you locate DNA matches.  For instance, if you know your mother was African and your father European, a found DNA Match with African ethnicity could be considered from your mother’s side.


Your released DNA matches list will state the country where each DNA match is located, and when you know that your parent was from a specific country, this will help you focus on DNA matches in that area or country.
