ThruLines™ shows you the common ancestors who likely connect you to your AncestryDNA® Matches—and gives you a clear and simple view of how you’re all related. When you link your public or private searchable family tree to your AncestryDNA results, new chapters of your family story may be revealed. You could see how your DNA Matches fit into your family tree and learn new details about the common ancestors who likely connect you.

ThruLines is supposed to be different, apparently based on DNA connections and meant to add new ancestors based on work done by other people. So I had a look.
I have a few things I wish Ancestry would address and they are marked below in red.
ThruLines tiles my screen with icons of over fifty ancestors, with about twenty marked with a green "potential ancestor" tag. (See the figure at the top of this page.) The icons are huge and would be easier to work with if they were a quarter the size or even smaller. I do not have photographs attached to my tree, but those who do see the actual people, not the pink, blue and grey generic images. I;ll probably add a few when I have a chance.
The "potential ancestor" tags are attached to named, known ancestors, as well as several categories of others.
There were four "potential ancestor" tags on known ancestors, eleven unknown but named people, six marked "private" and the one fifth great-grandmother with no identification. I immediately recognized four of the eleven as named known ancestors - two couples - that are flat out wrong because I know who belongs in those spaces. Somehow without my doing anything about it, one of the two couples has since disappeared. I'd like to know how that worked. And I'd like to get rid of the second couple. This is an example of a need for a "DISMISS" button
The four named, known ancestors
I have no idea why my great-grandfather Hersch Pikholz and my third great grandfather Simon (Shimshim) Rosenzweig are labelled as potential ancestors. I have both of them on my tree. ThruLines names people who added them to their trees - in one case a cousin Anne on the Rosenzweig side added Hersch Pikholz as a Rosenzweig father-in-law.
Incidentally, another researcher also added this same mother, Susanna, to Simon. When I wrote to him to clarify what his source is, he replied "There are 187,000 people in my family tree, data come mostly from the Internet. The data of Susanna and her relatives are derived from MyHeritage.com." Gotta be careful.
The third had no new information aside from the mention of a tree-owner who is a relative of my cousin Jessica's husband Matt. I have seen him in the hints and he is probably getting tired of my asking him who he is. In the meantime, the tag on that ancestor has mysteriously disappeared with no indication why. This is another example of a need for a "DISMISS" button - but if it disappears on its own, maybe not.
The fourth is Jacob Zelinka. my fourth great-grandfather. I know his father to be Leopold/Levko.ThruLines tells me this:
I know the five children listed here and descendants of three. The owner of the tree that ThruLines shows me has this tree for a client she has been working with for years and is limited in what she can tell me. But ThruLines also shows me this:
Three new generations for Etta Bryna?
My mother's maternal grandmother is my most recent brick wall. We know her father's given name and that he was a Levi. ThruLines adds a father, grandfather and great-grandfather - Juda Gurevich/Halevi, Shmerka and Urvater (=ancestor) Gurevich/Halevi - provided by a woman in Germany who does not identify her connection to these gentlemen. I have written to her and look forward to hearing what she has to offer in the way of evidence.
One of the private potential ancestors is the supposed wife of Juda Gurevich, Tojba Shpunt Spunt, who appears in the tree of my Borisov collaborator Galit. She isn't sure that Tojba really belongs there. I'll address this after I hear from the woman in Germany.
Gershon Kugel's parents
My mother's paternal great-grandfather Gershon Kugel's parents are quite unknown, but ThruLines has names for both - Khaim Kugel and Khana Gitla Kugel. My great-grandmother is Chana, so Gershon's mother's name makes sense. The information comes from a woman I have been in touch with previously and I am waiting to hear what she has to say about the new Kugel ancestral couple.
Her tree has my Chana, but not her known brothers. She also has a second wife for Gershon - Feyga Dvora Kugel and a daughter Sora Mina Kugel (b. 1857). That may work. In any case, there is no indication how the tree owner fits in here - or how she knows what she knows.
The Rosenzweigs of Trencin County Slovakia
My third great-grandfather Simon Rosenzweig, whom I mentioned above, is known to be the son of Solomon and I have long known of some descendants of his brother Nathan Joseph. The cousin Anne, whom I also mentioned above, is a descendant of Nathan Josef and she has promised to get back to me with more complete information.
ThruLines offers me a new generation - Herschel, the father of Solomon - and gives Solomon a daughter and four additional sons. Plus at least one generation of descendants for three of the additional sons.
The owner of the tree here is probably the best of the Trencin County researchers and he gave me his source information (without the document itself and without telling me where it came from). I will accept Herschel and his children on that basis. As well as the new descendants of Solomon.
Oh, and Hershel has another son, Moses with two wives and ten children. Lots of new good information here.
Lesson learned - you cannot assume the ThruLines connections to be correct. You must check them one by one. You can decide to trust specific researchers, but you must be very careful.
Oh, and one more thing. Now that Ancestry has decided that Herschel Rosenzweig is the father of Solomon - which is almost certainly correct - their old-style hints have brought me more than half a dozen other researchers working on the same family. I have dropped notes to all of them.
Keep in mind, if Herschel is wrong, I would still be getting all these new hints to follow up with. Be careful out there!
One more note - they tell you who has done DNA testing but there seems to be no real use of DNA in the ThruLines algorithms. But make no mistake about it, ThruLines is a valuable tool. Keeping track of new developments may be a chore, plus of course running after the other tree owners to figure out what is right and what is false.
European Jews have always married mainly within the tribe. Whether our numbers five hundred years ago in Europe were four hundred or four hundred thousand, the pool was limited. As a result, the members of the tribe today are all related to one another, multiple times. This phenomenon, known as endogamy, makes Jewish genetic genealogy very difficult, often impossible. There is a similar phenomenon in some other population groups.
I was convinced that this brick wall is not as impenetrable as it seems, at least in some circumstances.
I believe that this book demonstrates that I was correct.
When I decided I wanted to write a book, I was not sure if I wanted to write a “How to” book or a “How I did it” book. The decision was dictated by the facts in the field. Different family structures, widely different numbers of living family members, and other similar factors dictated that writing “How to” would be irrelevant for most researchers.
“How I did it” is more likely to be helpful to the research community and more likely to instill the confidence necessary for such a project.
It is my hope that this book will encourage and inspire other researchers of their European Jewish families and other endogamous populations to say “I can do this!”
