Ancestry DNA Thrulines Overview

Are you interested in expanding your family tree? Consider employing Ancestry ThruLines, a recommended tool by genealogy researchers. This tool allows you to identify DNA-tested relatives and matches, significantly aiding in the growth of your family tree. With a simple click of a button, it uncovers matches that would otherwise take a considerable amount of time to discover, streamlining your genealogical research.

What is Ancestry ThruLines?

  • Ancestry ThruLines is a tool that identifies DNA-tested relatives and matches based on the data in family trees.
  • Its accuracy depends on the correctness of the data in family trees; errors can result in misleading ThruLines.
  • ThruLines can be viewed by the user and invited DNA results viewers. However, if a tree is private or unsearchable, ThruLines and match results will be unavailable.

Are Ancestry Thrulines Accurate?

It is essential to note that Ancestry ThruLines’ accuracy relies on the correctness of the data in family trees. Inaccuracies can lead to incorrect connections and misleading results. Therefore, it is advised to verify suggested matches from ThruLines.

How To Explore Ancestry Thrulines

John Berger & Eva Lenz were great-great-grand parents of my family. One of my researcher has discovered a unique information deal regarding Eva’s parents and the increased family, but I didn’t spent a high time to research about John. He is from Mecklenburg, Germany to Minnesota as adult. And it is not known to anyone that any of his siblings or related family who came together with him. John buried in the cemetery at Lutheran church from where the family has generation history. Personally, I have not verified the burial registers of church, but a distant relative from the family has reported the names of John’s parents listed there.

Many descendants of Eva & John are in my Ancestry DNA matches list on various authorized testing websites.  I make use of shared matches’ features to find out other DNA matches who shares DNA with me or with any descendants of Lenz/Berger.

Ancestry Relationship View

Ancestry ThruLines has two kinds of views i.e. Relationships and List. Relationship view offers a graphical view of descendant’s available ancestors.

The default view of John Berger displays your connection to him although it is possible that some details may be collapsed, and other DNA testers who are the only descendants of a child of that particular ancestor. DNA data may collapsed for all children of that targeted ancestors but can only be expanded by pressing on the “#DNA matches” link under the name of child.

To review the detailed information for a specific line, press on “5 DNA matches” available below their name, which may result in the below given view.

Relationship View

This will offer the information of ancestral path to each of the DNA matches from the particular family, their relationship, and the DNA amount shared with them.

Default relationship view of John displays about the descendants of John’s children has tested. John and Eva had total of six childs. Four of them are listed here (Carl, Gustav, Emma, and Otto) with a daughter Bertha and a son Henry. The son henry died in age around 20 years and had no children. I had done a research on my DNA results to find out Bertha’s descendants in case those are detectable by Ancestry ThruLines.

Relationship View 1

Bertha’s family is big and most of her children had children. The lack of tested descendants shows a research opportunity for ThruLines. Bertha likely to inherited some of the elements  of John’s DNA that her sibling may not have so it may be a beneficial research for this family if her descendants also available in the testing databases.  In the earlier research, I found only 14 of Bertha’s grandchildren who born between 1912 & 1938. If we focus on the younger grandchildren it may be a best technique to search for available testers. If no grandchildren are available, then recruiting the great-grandchildren is also a better option.

Ancestry DNA List View

The List view also displays the descendants list similar to the relationship view but all those are in a single list. While using Relationship view, if you expand a single line then other lines may automatically contract. Whereas, List view offers “a glance view” with all the DNA relationships and included shared DNA matches information.

List View

Seeing the Ancestry DNA relationships data and amount of centimorgans shared with ancestors for all the relatives at a single place offers a great benefits to cross-check for your ancestry family tree and also for family trees of your DNA matches. If the predicted DNA relationships and centimorgans are not found consistent with each other, then it is possible to have errors in your family tree or the other people trees that you have used to collect DNA data. This type of descendants view can sometimes make only half relationships more apparently then they actually are by viewing the individual DNA results.

How to Get Ancestry DNA ThruLines

  • Firstly you need to take the Ancestry DNA test.
  • Opt for the features to see & be seen to DNA test.
