Fun With an AncestryDNA Lentz Circle

My Lentz Line has been difficult to nail down. The genealogy has been difficult and it has been difficult to assign a lot of DNA to Lentz ancestors

My Lentz Circle at AncestryDNA

Ancestry has been helpful in the Lentz area. Here are my AncestryDNA Circles:

Lentz is one of my smallest circle with 9 members:

Six of those 9 members are from my family. That leaves two other groups with a total of three people in them. In the Deborah Family group, there are two Deborah’s. They appear to be mother and daughter. I built out the tree of the mother and found a common ancestor in John Lentz. Then I found the tree of the daughter Deborah and she had already built out her tree as seen here:

John Lentz is on the younger Debbie’s mother’s father’s father’s line or her great-grandfather Davenport’s Line. This matches up well with my Lentz Web Page:

I was unclear as to whether John had one or two wives. Debbie has identified the wife as Elisabeth Riehl. I didn’t follow the line down of William Andrew. However, I have more information on my Ancestry Tree, which puts my Web Page out of date:

 

Lentz DNA

One interesting thing is that I do not match either Deborah at AncestryDNA. They do, however, match my mother and some of my siblings. Here is my mom’s match with the elder Deborah:

What is more interesting is that the younger Debbie uploaded her DNA results to Gedmatch. This is what the match looks like between Debbie and my Mom:

By DNA, my mom, Gladys and the younger Debbie could be fourth cousins. However, Debbie and her mom match my mom at about the same amount of DNA. That means Debbie’s mom passed down all the Lentz DNA that matches my mom to her daughter. This DNA match is on the shortest Chromosome.

Visual Phasing for My Siblings – Chromosome 22

I performed visual phasing on my DNA. Here is what I had for Chromosome 22:

This matches up with what Gedmatch shows as Debbie’s matches with my family:

In this case the reportable matches start at about 15M, so that is where Jim, Heidi and Lori have Lentz DNA shown in green on the left hand side of my Chromosome 22 map above.

A Lentz DNA Tree

I have drawn a tree of the Lentz descendants who have had their DNA tested. I had missed Debbie, so she is not there yet:

I am on the left side of the tree. I also descend from the Nicholsons and get a lot of matches with that family. The right side of the tree is more specific as I have no Nicholson relatives there, but the relationships are further out. I am already tracking two people from the William Andrew Line there.

Here are the two Deborah’s added in:

This shows that my mom is a fourth cousin to the elder Deborah and I am a 5th cousin to the younger Deborah.

Here is how Debbie matches Radelle, Al and Stephen on Chromosome 12:

This suggests triangulation between these four people which would indicate a common ancestor:

My mom matches Radelle and Deborah, but on different Chromosomes. Hence, the Ancestry Circle.

Painting Debbie’s Match to My Mom

This is what I had previously for my mom’s John Lentz DNA based on her match with Radelle. That match is in dark green.

I need to add Mom’s Lentz DNA to Chromosome 22:

This doesn’t look like much, but it doubles what my mom had on Chromosome 22 previously.

Summary and Conclusions

  • Reviewing my AncestryDNA Circles lead me to a Lentz descendant who I had overlooked.
  • One of the people in the Circle had uploaded her DNA to Gedmatch. I had seen her match before, but didn’t know exactly how we connected on my mother’s line.
  • Because Debbie uploaded her DNA to Gedmatch, I was able to tell exactly where she matches different Lentz descendants.
