When the same name or family comes up in ancestors of DNA matches

Can two siblings with the same parents have different AncestryDNA?

So yes, it is definitely possible for two siblings to get pretty different ancestry results from a DNA test. Even when they share the same parents.

What does shared matches mean on AncestryDNA?

A shared match is someone who appears both on your list of matches and on someone else’s. For example, if Frank and his uncle Darnell both have Frank’s sister Angela on their list of matches, Angela is a shared match. You can see which matches you share with 4th cousins and closer.

Can you have a DNA match and not be related?

Yes, it is possible to share a small amount of DNA with someone and not be related. In other words, it’s possible to share genetic material and not share a common ancestor or any identifiable genealogical connection.

What is a common DNA ancestor on Ancestry?

A Common Ancestor Hint indicates that your DNA match has a direct ancestor that matches the name of one of your direct ancestors. In other words, a Common Ancestor Hint means that the Ancestry software has identified a shared ancestor between you and the DNA match.

Will my sister and I have the same AncestryDNA?

Because of this, siblings’ ethnicities can vary. All the genes passed on to siblings come from the same gene pool (that is, the genes of both parents), so each ethnicity passed on to children must be present in one or both parents as well.

How do full siblings show up on AncestryDNA?

Full-siblings are separated by two degrees of consanguinity (count one up to get to the parents, and one down to get to the other sibling = two). Half-siblings will share the same amount of DNA as people who fall into the “3 degrees of separation” category, which on Ancestry is the Close Family category.

What are featured DNA matches on Ancestry?

We compare your DNA to the DNA of every other person in the AncestryDNA database, and based on how your DNA matches up, we estimate how closely you’re related—whether you are siblings, first cousins, distant cousins, or not related at all (see figure 1).

How do you know if a DNA match is maternal or paternal?

A Y-DNA test examines the genetic code located on the Y chromosome, which is only found in biological males. Since this chromosome is inherited exclusively from the father and never from the mother, the DNA analyzed on this type of test will give you information that is specific to the paternal line in your family.
