My First Six “Cousin” Matches on AncestryDNA

I have hundreds of cousin matches on AncestryDNA. I’m not yet certain how many I will eventually try and contact.

The first six matches were particularly interesting for me  as  AncestryDNA grouped them as “second cousins.” The first five matches were indicated as being “first or second cousins” and the sixth was indicated as being a  “second or third cousin.”  A little quick review:

  • first cousins share a set of grandparents
  • second cousins share a set of great-grandparents
  • third cousins share a set of great-great-grandparents

Given my family structure and precluding any “surprises,” I probably knew the second cousins personally or at least knew who they were even if we have never met. My experience is based upon my own family and may not be representative of the experiences of others.

I only have three first cousins and did not expect that they had taken the test. That meant that these first six matches (assuming they were actually second cousins or closer) were descendants of one or more of great-grandparents.

Of my first four matches, the identity of the first two were known by me simply by their username. They were first cousins of my mother (on her paternal side) and are half-siblings of each other.  This makes them first cousins once removed to me (consistent with the range given by the AncestryDNA results). They took the test mainly for reasons of ethnic curiosity. I did not contact them via the messaging on AncestryDNA because I knew who they were and am already friends with one on Facebook.

I contacted the third match via the messaging on AncestryDNA. She is a first cousin of my mother (maternal side) and was someone of whom I was aware. I’m not certain how interested she is in genealogy, but she did respond within twenty-four hours to my request. She would be my first cousin once removed.

The fourth match was for a first cousin of my father (on his mother’s side) with a test administered by his wife. Based upon the username and the pedigree I was able to determine who this person was. Since we are already in contact, I did not see a reason to contact again. He would be my first cousin once removed.

Identifying details removed for privacy reasons

The fifth match was from a test administered by the daughter of the donor. She responded within twenty-four hours to my email telling me who she was. The donor is a first cousin to my mother (maternal side) and would be my first cousin once removed.

The sixth match was from a test of someone with whom I am in communication already. In fact, her mother was somewhat involved in genealogy years ago. The grandmother of this match is a sister to my paternal grandmother. This makes her my second cousin.

I really did not expect the AncestryDNA relationship determinations to be incorrect. In this case, the responses may have been quicker given that I already knew some of these people and that we are fairy closely related.

It is important to remember that people take AncestryDNA  for different reasons. Some want to simply determine their ethnic ancestry and others interested in their genealogy. It is worth noting that some who are interested in their genealogy have a passing interest. Some are rabidly obsessed. That partially impacts the speed with which one gets a response as do non-genealogy commitments that many people have.

One thought on “My First Six “Cousin” Matches on AncestryDNA

  1. Hi,
    I wanted to share an experience I had on Ancestry DNA. My husband, myself and our 3 adult sons all took the test, then I recently talked my sister into doing it (along with her husband). I am the administrator of all of the accounts. I received a message asking me what I knew about a particular person who is my great grandmother’s brother. We began communicating and discovered we are second cousins once removed. He is on my sister’s first page of matches (they share 109 Cm of DNA) listed as 2nd or 3rd cousins. I find this man on page 17 of my matches as a possible 7th or 8th cousin!!! (We only share 16.7 Cm of DNA) That was so shocking to me!! Obviously, my sister and I are both 2nd cousins once removed with him. So although I can’t go through hundreds and hundreds of matches looking for surprises like this, I am so grateful I got my sister to do the test because that’s how we “met” this man. We are in constant communication trying to put the pieces of our family together because we both knew very little about them.
