To find an unknown parent or grandparent, start by sorting your DNA matches into groups. Many companies help you do this sorting by using a shared or “in common with” feature to show you matches that share DNA with each other.

Choosing the DNA Test
If you quickly identify a close family member, such as a first cousin, a simple email exchange will be enough to identify the grandfather. In most cases, you will have distant relatives.
If you wish to connect with your biological family or determine an unknown parent, consider taking an autosomal DNA test. An autosomal DNA test can be taken by males or females and may provide you with DNA matches within 5 to 6 generations on both your biological mother and father’s sides of the family.

You can take a middle name or a first name and look in census records for people with the same last name in the general area who are old enough to be your ancestor’s parents or grandparents. You can also take a middle name and look for people in the area with that name as their surname.
Ancestry DNA results can help indirectly reveal your paternal line. If your father has not done a DNA test with Ancestry DNA, then the website will not be able to tell you directly who your father is. Even so, you may be able to determine who your biological father is based on your closest DNA matches.
Unlike Ancestry, 23andMe does have FDA approval as a risk screener for a handful of genetic conditions and diseases — if you’re primarily interested in DNA testing for this purpose, 23andMe is the better choice. The app tracked my sample’s journey to the lab and the DNA extraction process.

Grandparents and grandchildren
Your grandparent shares 50 percent of their DNA with your parent, who shares 50 percent of their DNA with you; likewise, you share 50 percent of your DNA with your child, who shares 50 percent of their DNA with your grandchild.
That doesn’t mean Ancestry is not going to tell you that you’re related to famous people. However, there’s a caveat. The celebrities have to have tested and made their results publicly searchable. This pertains to living famous people that you might be related to and if they’ll show up on your DNA match list.
Based on how your DNA matches up, Ancestry estimates how closely you’re related—or if you’re related at all (see Figure 1). And if you’ve opted in to AncestryDNA Matching, you’ll both be able to see your matches and be displayed as a match to others in the database who are related to you.
