DNA Testing to Identify a Biological Father - Your Guide to DNA - Diahan Southard (2023)

Do you have an unknown biological father or mother? Here's what you need to do to use DNA testing to identify your unknown biological father, or at least get more information about that father's family tree.

DNA Testing to Identify a Biological Father - Your Guide to DNA - Diahan Southard (1)If you have a known parent and an unknown parent, you can use a very simple process to identify your unknown parent, or at least learn more about that parent's family. I'll explain this process using a real-life scenario, with details changed for privacy reasons. But you can also follow these steps and adapt them to your own situation.

DNA test to find a biological father or mother

I know a woman, let's call her Lora, who is looking for her biological mother. Lora was raised by her birth father, but all she knows about her birth mother is that 80 years ago, when Lora was born, she was working with her father at a Ford Motor factory in Detroit. Circumstances were such that Lora's mother was forced to hand her over to her father to raise.

Lora suspects that her biological mother has probably died a long time ago, but she would still like to know who she was. She decides to get oneautosomal DNA test.


DNA Testing to Identify a Biological Father - Your Guide to DNA - Diahan Southard (2)Lora keeps testingAbstammungs-DNAbecause its huge pool of tests increases your chances of connecting with close DNA matches. Knowing her biological father's family well, she researches and creates an online family tree for him at Ancestry.com. In this tree, he only identifies his biological mother as a "biological mother" who has lived in Detroit for 80 years. (Here are more tips for creatingthe best tree online for your DNA profile.)

She receives the results of her DNA test...

When Lora receives the results of her DNA test, she links them to her family tree. Then she goes to the DNA homepage and selects the option to View all DNA Matches. As this is an autosomal DNA test, matches from her will include relatives on her mother's side and her father's side. She has to separate these coincidences.

DNA Testing to Identify a Biological Father - Your Guide to DNA - Diahan Southard (3)The easiest way to do this is to identify matches in yourof Fatherside (of which she understands something) and put it aside. Beforehand, she clicks Groups > Create Custom Group at the top of her mailing list and creates a group called "Mother Page". Repeat this process to create a group called "Daddy's Side". She chooses different colors to identify each group.

Lora then looks for the closest possible DNA match that she can see from her father's side. Ideally, she would have her father, her father's brother, or that father's own brother also take the test.ancestry.But she doesn't have that option, so she looks for familiar names and faces in the list of usernames and photos. (If you don't find a close match here, use the search box to find your last name and your mother's maiden name in the match tree fields under Match First Name and Last Name as shown below. Lora can expand this search for additional surnames of your ancestors.)

Lora identifies a close DNA match on her father's side: a first cousin. He clicks the Add/Edit Groups box next to this mailing's username and adds it to the Parent Side group.

Then select from that game's profile pagecommon games🇧🇷 This shows everyone tested at Ancestry who shares DNA with her and this relative of your father's. Lora scrolls through the list of shared matches and adds them to the Parent's Side group using the Add/Edit Groups option to the right of each of her close matches (4th cousin or nearest). When finished, it will return to the group's main page. Any remaining close matches without the parent page tag are added to the parent page group.

(Note: If Lora's biological parents were genetically related, this process wouldn't work. She initially assumed that wasn't the case.)

Working with DNA Matches of an Unknown Biological Father

Now that Lora has separated her biological mother's DNA matches from her father's, she can focus on the former. Under Groups, select the Parent Site group and start reviewing this mailing list.

It is possible for Lora to see a very close relative, such as her own biological mother or a half-sibling.ancestryThey can be identified based on the genetic distance between them. But your closest matches tend to be in the range of first cousins ​​to fourth cousins, which happens. Few of them have posted trees and few have responded to the messages she sends. Discouraged, she puts the search on hold for a few months.

But not forever.It's good to be back because in the meantime another great DNA match has surfaced...

Read what Lora discovered and what her next steps should be.

    Excellent article. Your scheme is very similar to the approach I used. Although my efforts (20 years) to discover my biological father have been unsuccessful, I am fully aware of the waiting game side of the equation. I believe that a large proportion of people who unsuccessfully search for "unknown" often have unreasonable expectations. I would tell these people that all is not lost. As the popularity of DNA testing grows, so does the DNA database. Sooner or later, that elusive giver will show up. Thanks for a well written explanation.

    Diahan, if I bring all the matches to my known match on my mother's side, I would have about 10 matches. This left thousands of leftovers, some of which must be part of the mother site. If I take all the leftovers and put them on the father's side, am I kidding? Should I find common matches with each of the ten people and add more people to Mom's list? and go on like this until there are no more matches left for mom to share?

    1. I have a similar but more complicated case. My biological mother is Asian, Korean or Japanese, and I was born in South Korea. My father was an American-born white American who brought me to the United States from South Korea in 1955 on his American passport. He was an only child and died in 1979 before DNA testing was available. His parents are all dead.

    2. I don't have a birth certificate and can't get one because:

      (Video) What to do with your DNA Test Results in 2022 | Part 1

    A. I don't know who my Asian biological mother is;

    B. If you are Korean, according to the US Embassy of Korea: Only male Korean citizens can and must report the birth of a child born in Korea (husband, uncle, cousin, brother or son). My father was an American citizen;

    1. My birth name was given to me by my biological father and they are names in English/French/German and also in that order (first name, middle name and last name).

    2. I have many problems with incorrect information about myself on the Internet and in various places, even DNA and genealogy databases received and stored incorrect dates of birth, addresses and information relating to me. I know this because I paid for the My Heritage DNA test but I gave up after finding your website about me ignoring the information you provided as correct and replacing it with WRONG DOB, FAMILY AND ADDRESSES from your archived databases even before I registered and paid for the DNA test (this is the main reason for my rejection. I offered to mail proof of my name and date of birth and other confidential documents, but I was given an address in Israel that was correct .) single address So I refused to ship my confidential life records outside of the US and so again I couldn't clear the wrong date of birth etc. with me.

    3. My driver's license and ID have been stolen from me several times in the past due to thefts and people using my name to get credit cards, money, etc. illegal use of my name. Fortunately, in the state of CA where I currently reside, as long as you know your driver's license number and your CA DMV photo matches what's in the CA DMV registration database, you can get a replacement driver's license. (or earlier) and how I make my IDs according to Compensated Theft).

    4. But since the September 11, 2001 terrorist attack, credit bureaus and most government agencies require a birth certificate, which I don't have and can't get because birth certificates are based on the mother's information.
      the dilemma and the need to know the biological mother.

    I have tried to get help from lawyers, legal centers, etc., but no help.

    1. World databases have limited Asian DNA databases and my father's other children who were born in the USA from different biological mothers refuse to help me or to take DNA tests to prove that we have the same father.

    2. If the US also created birth certificates for the biological father and not just the mother, I wouldn't have as much trouble correcting birth certificates, addresses, etc. wrong, either by fraud/identity theft, etc.
      I could get Medicare health insurance and my retirement would accurately reflect past earnings and I wouldn't have to constantly fight false birth dates and false information about myself.

    3. My name and correct date of birth are listed on the immigration documents that my father filled out in Michigan in 1965 when I was 5 years old, but immigration did not complete the process and said that immigration requires a marriage certificate which my father means that my biological mother got married and also needed a delivery. Certificate of completion of the immigration application process; Things my father couldn't produce.

    4. I also know my correct name and date of birth from Michigan Juvenile Court records because I was tutored by the court and state of Michigan after my father divorced my stepmother in 1965.

    So how can someone with my complicated life get help through DNA and what types can I get if I don't have a stepbrother to help me?

    I don't know where to go, I know my biological mother and her side of the family. All I know is what state they were in when she got pregnant and that my biological father lived next door. Apparently Native American, he was married with 9 other children. My mom doesn't talk about it and my grandparents died before I could ask. My aunt and uncle were too young to remember all the details. My birth certificate lists my mother's husband as the father and I was born in a completely different city and state. I was 20 when I was told my dad wasn't my dad. Where should I start? I don't have a lot of money for tests and kits, but before I die I want to know where I'm from. I just need a little guidance.

The lab compares the tissue samples from the mother, the child, and the man to see what special characteristics – known as “genetic markers” – the child shares with the mother and the man who may be the father. These tests are very accurate in showing whether or not the man is the biological father of a child.

How do you know if you are the biological father without DNA? ›

How much DNA does a child share with their biological mother with their biological father? ›

Every child gets 50% of their genome from each parent, but it is always a different 50%. During meiosis, gametes get a random chromosome from each pair. This means that there are over 8 million possible DNA combinations from 23 chromosome sets!

Does your bloodline come from your father? ›

Among the many things parents hand down to their children are 23 pairs of chromosomes – those thread-like structures in the nucleus of every cell containing the genetic instructions for every person. We inherit a set of 23 chromosomes from our mothers and another set of 23 from our fathers.
