My Mom’s Lentz Family and Roberta Estes’ Lentz Family

Roberta Estes has blogged about her Lentz family. I have also blogged about my Lentz family. Roberta and I have checked to see if there was an autosomal DNA match between our two families, but we were unable to find any significant match. Recently, in checking my 23andMe results, it seems like there may be a way to see if we are related by YDNA.

My Mom’s Lentz Family YDNA

I have tested my DNA at 23andMe and have a few Lentz matches there. One good thing about 23andMe is that when you take an autosomal test, they also give you a rough estimate of your YDNA haplogroup. I have has two Lentz matches at 23andMe who are brothers. They both have this Haplogroup:

I’ve sent off messages to the two brothers. I don’t know exactly how we are related, but based on the size of the autosomal DNA match and where they live, my guess is that our common ancestors must be Jacob George Lentz and Annie Nicholson:

I don’t have record of William Lentz born 1892 as having any sons. William did have a brother named Stanley who had sons, so that may be where the two matches fit in. At any rate, their YDNA would go up through the Lentz side.

What is R-Y4355?

I would expect that 23andMe has an accurate haplogroup though not recent. Here is what YFull has on Y4355:

Above the tree, YFull gives the YDNA Line for this branch of Lentz back to Genetic Adam (listed as Home). This shows that Y4355 is about 4200 years old, so fairly old. I recognize R-U152 in that line as a major branch.

Roberta Estes’ Lentz YDNA

Here is what Roberta has in one of her Blogs:

Roberta has invested in the Big Y test for her Lentz relatives, so this is likely to be extremely accurate and fairly recent. YFull does not have BY39280, but has some information on KMS75:

Actually KMS75 is listed as +1SNPs above. The equivalent at YFull is Y20993 which was formed 4800 years ago. So this particular SNP is not that recent. BY39280 would be more recent but perhaps not by much.

The Short Answer

I would say that based on the 23andMe Haplogroup and the work that Roberta has done, these two families are not related. The common ancestor is R-L23 which was formed 6400 years before present. I’ll draw a tree for the two Lentz families:

I would have thought that Roberta’s Lentz Line would be longer, but it must be an older branch or a branch with less branching in it. So from the top of the tree to the bottom is about 2,000 years, but we still have about 4,000 years to get to the useful genealogical time.

Here is an R1b Tree:

I have an arrow pointing to where my Mom’s Lentz family and Roberta’s Lentz family split. The split goes to Western Altantic for my Mom’s Lentz family and Eastern for Roberta’s Lentz family. Interesting. U152 is a major branch. U152 begins below the ‘ic’ of Atlantic. Checking the YDNA was pretty easy. That concludes the YDNA part of the Blog. Next I’ll add my Lentz autosomal DNA to DNAPainter

Adding Lentz DNA to DNAPainter

I can add the autosomal DNA to DNA Painter for the two Lentz matches I have at 23andMe. Here is one match added to my Lentz/Nicholson common ancestors:

Jereme adds important DNA that I didn’t know about before. I didn’t have any DNA from these two common ancestors previously on Chromosomes 2, 3, 4 and 15. I have less of a match with Jereme’s brother Will:

I’ll paint in Will also even though he doesn’t add new information. Jereme matches me by 95 cM compared to Will’s 72 cM.

Jereme and Will upped my percentage of maternal mapped DNA from 30 to 32%. That is a significant jump at this stage of mapping:

Here is the maternal and paternal side:

I changed Lentz/Nicholson to a sort of pea green because it was the same blue as Clarke on my paternal side. I now have 41% DNA painted overall. I assume that this went up although I didn’t check to see what it was previously.

Summary and Conclusions

  • 23andMe has a useful feature that predicts your YDNA Haplogroup at no extra charge.
  • This feature can be used to see if you are related to male relatives of the same surname. In this case, I was related to two Lentz brothers with a predicted haplogroup. Roberta Estes had Lentz relatives tested for YDNA resulting in a known Haplogroup. I checked on Roberta’s Lentz relative’s YDNA haplogroup and it didn’t match up with my Lentz relative’s Haplogroup. I then found the common Haplogroup for the two Lentz families. The common haplogroup was over 6,000 years old.
  • It would be interesting to see if this could be used in other situations.
  • This Blog was short so I painted the autosomal DNA of my Lentz relatives using DNA Painter.
