A few days ago, I received a note from someone who descends from my Miller line. Specifically, from our common ancestor, Philip Jacob Miller (1726-1799) and his wife, Magdalena (1727-1808).
Many records give Magdalena’s surname as Rochette, but I have found not one shred of evidence as to that or any other surname, nor can I find where the information about the Rochette surname originated. So call me stubborn, but until there is some sort of proof, I’m not using it. I will say one thing though. Philip Jacob Miller was Brethren, as were his parents, and it’s very likely that his wife was also from the Brethren community – and there was no Rochette in the Brethren community or even in the same county. And yes, I’ve personally checked the records.
Philip Jacob Miller and wife Magdalena had two sons, David, who my newly found cousin descends from, born in 1757, and Daniel, who I descend from, born in 1755. My cousin and I had “met” on 23and Me a year or so ago, but since she was not at Family Tree DNA, she could not join the Miller-Brethren surname project and I couldn’t compare her results to those of other known Miller descendants. The Miller-Brethren DNA project focuses on the Miller families who were members of the Brethren (or similar) religions – and yes – there was more than one genetic Miller family – even in the same county and congregation. They even moved cross-country together, yet they were not all from the same Miller ancestral line. Y DNA busted that assumption years ago, but it was not at all what we expected to find!
When I received a note from my cousin that she had taken advantage of Family Tree DNA’s (almost) free transfer opportunity, I was thrilled, because we could then compare her to the rest of the clan.
In the Miller-Brethren project, we have three other cousins, all of whom descend from Daniel Miller in one way or another, that my cousin matches. Her best match is to my mother with 82 shared centimorgans and next, with me at 64.
You can see the comparison on the chromosome browser, below, at the default thresholds. Green is my mother, orange is me and blue is cousin Herbie who descends from another son of Daniel Miller. You can see that there is a very large chunk of DNA on chromosome 14 where we all match. A fourth cousin, shown in pink, also descended from Daniel, does not carry this segment of DNA on chromosome 14.
Dropping the threshold to 1cM produced more matching segments, but still no pink on chromosome 14, so clearly our pink cousin did not receive any Miller DNA on chromosome 14. However, we can attribute a huge chunk of chromosome 14 to Philip Jacob Miller and wife, Magdalena. This segment is quite large, a total of 48cM and 12,894 SNPs.
A second very interesting match is on the X chromosome. It’s fairly large too, a total of 11.84cM broken into three segments. You can see that both mother and I match my cousin on the same X segments – obviously from Philip Jacob Miller and Magdalena. Right? Wrong. Wrong. Very wrong.
If you’re scratching your head about now, you’re not alone. Keep reading…
Do you ever just get a sense that something isn’t right? A second sense that you need to check again? Well, in genetic genealogy, never assume. After I thought for just a second, I decided to grab my X chromosome map, because something just didn’t seem right. So glad I did, because Philip Jacob Miller and Magdalena are NOT on the X inheritance path of my mother (and therefore not me either) so the X match CANNOT come from them.
Using Charting Companion software, I can easily see, in pink and blue, who my mother’s X chromosome comes from in her lineage. You can also see that Philip Jacob Miller isn’t on the X path, and neither are his descendants for two downstream generations – not until David Miller’s wife, Catharine Schaeffer, brings her X to the game. So, the X match cannot be through this Miller line.
So, where did it come from?
In addition to this chart, I also sent an X chromosome pedigree chart to my cousin. She looked it over, and made a discovery.
Moving to my grandmother’s X chart, because the print is too small to read if I add another generation on my mother’s chart, you can now see Maria Magdalena Weber.
Maria Magdalena Weber was born in 1724 in Mutterstadt, Germany to Johann Martin Weber and Maria Magdalena Schunck.
As it turns out, my cousin has another ancestor Eva Maria Weber, born in 1709, someplace in the Phalz portion of Germany, first found in Oley, PA. Now, it turns out, that Oley, PA is also where some of my other ancestors lived. The DeTurks, Hochs and Deharcourts married into the Schaeffer family who migrated to Montgomery County, Ohio and married into the Miller family. And yes, for those who are wondering, the Schaeffer line IS in my X path and yes, there are brick walls there that need to fall.
Looking back at the first fan chart, Catharina Schaeffer is the wife of David Miller, son of Daniel Miller, son of Philip Jacob Miller and Magdalena. Yep, it’s a small world. And truth is stranger, sometimes, than fiction.
So, is our common ancestor a Weber? And if it is a Weber, is it from the Mutterstadt Weber line, or is it a mystery person from Oley, PA – a brick wall that hasn’t fallen yet?
We don’t know.
We’re still working on it.
Now all I need is a tool to find every other person who matches me and my cousin on that same X segment and see who their ancestors are.
Webers or Oley, PA people, or both????
Or are they one and the same?
Webers who are from Mutterstadt and who went to Oley, PA and…
would it be…
could it be…
possible that I descend through that line twice????
Oh, my head hurts.
The genealogy Gods certainly have a perverse and twisted sense of humor.
The lesson here is never assume. Just because you have positively identified your common ancestor with a match, and proven it with triangulation, doesn’t necessarily mean that is your ONLY ancestor that you share with that match. You know what assume does.
Among other things, it gives you a headache.

Fascinating!! I must get myself Charting Companion and Genome Mate. But first I will need to check if they will work with RootsMagic.
The people at AncestryDNA need to read this post. The love making assumptions. And they apparently don’t think triangulation is important.
Love this post. Have been working on a bunch of 5 cousins who all for a tight matrix. It looked like it was all from a Wilhite/Boydstun match but there are a couple of lose ones in the deck????
And the matches are on the wrong side of the family for my cousins that match! Intrigueing isn’t it. And don’t we just wish we knew MORE!
Very interesting Roberta. I will certainly buy the Charting Companion software if it is compatible with Ancestry. I used to use PAF but found it was more convenient to use Ancestry.com.au. Being an Australian, Ancestry doesn’t allow us to use their DNA testing arm, but I’m in touch with many of my DNA relatives on 23andme and agree that sending them 12 generations is a great idea rather than inviting them to my Ancestry.com.au tree. I’m particularly interested in the charts for sending to people who share the x chromosome. If it’s not compatible with Ancestry, can I just print out the charts and fill them in manually?
I don’t know Merilyn. Check out the Charting Companion website and ask the owner if any question.
Thank you for this post on the Miller-Brethren. I now have another place to look for my Miller family. My cousin and I have been try to find our Miller family and are using my maternal uncle’s Y-DNA and three cousins autosomal DNA to find our Miller line. Will it help to use the Lazarus tool to recreate Miller DNA?
I have only played with Lazarus a little. I would say that it would help, but maybe you could experiment some and see.

How would I know if my Grandfather Miller was a Miller-Brethren? Is there an uncommon SNP? If so I can look at my Uncle Loren Miller’s Y-DNA and see if there is something there.
Hi Tia, If you have knowledge of the family being Brethren, that would be a huge clue. Secondly, you have join your uncle to the Miller-Brethren project. There are distinct signature groups that are Brethren. You can see it here. https://www.familytreedna.com/public/miller-brethren/default.aspx?section=yresults
I have not joined the Miller-Brethren for my uncle but I will.
Under matches, search by project and see if he has any matches within the project. If so, you’ll need to check and see if they are in any of the Brethren groups or if his match is in the nonBrethren group (who really shouldn’t be in the project at all.)
My uncle showed up in the nonBrethren grouped section of the project. I will not be offended if you have to take him out or can I do it myself? He seems to have at least 10 differences from the one listed as Brethren.
Hi Tia. I just checked and he does not match anyone in the project. I’m sorry. But thanks for checking – you never know. I’ll unjoin him for you:( Roberta
Thank you and sorry for the trouble.
No trouble Tia.
Very interesting, and very complicated. One of the things that popped out at me was the fact you are a descendant or DeTurcks and DeHarcourts??? They are also my ancestors.
I would love to exchange info about them. I’ll e-mail you.
Another reason AncestryDNA needs to allow chromosome browsing. I’ve found quite a few of these ‘double matches’ with the help of chromosome mapping on gedmatch.com

This kind of multiple-relationship problem haunts me as I work with my Norwegians. I don’t think they’re exceptionally endogamous, but they’re bound to be somewhat so in isolated areas. And most of my relatives who are related through non-Norwegian ethnicities are also part Norwegian. My paternal first cousin (German + Norwegian) is also my maternal third once removed (Norwegian) AND there’s a segment where she is fully identical. At least we KNOW about the relationships there. I anticipate learning that some of the other relatives are related on both sides too. But it means filling out more of their trees.
