Fixed – Attaching DNA results to family trees
Last week, we reported on the overwhelming popularity of attaching DNA results to member’s family trees and the latency that the tree propagation feature was experiencing. Today, I am happy to report that the latency and intermittency has been fixed. Once DNA has successfully been attached to the first person, the DNA results will, for most, be instantly inferred up a lineage for a maximum of 20 generations and down a single generation. In the event of an adoption, DNA can easily be detached from the individual, thus stopping the propagation.
Three types of DNA may be represented on a tree:
- Actual. DNA attached to the node from an actual participant.
- Inferred. DNA that has been propagated up or down a lineage.
- Copied. DNA that was “found” and copied from one node to another. (This is like finding a birth certificate or picture and copying it to your tree.)
To attach DNA to your tree, follow these steps:
- Login to www.dna.ancestry.com.
- From the Ancestry or View DNA Results pages, click on Attach Results to Tree (on the right hand side of the screen.)
- Accept the Content Submission Agreement and then choose Attach.
- Attach DNA results to someone in your tree by selecting the appropriate tree and choosing the appropriate person within the tree.
DNA results and an indication of the type of DNA will be noted in the Person Profile page of all relevant family members.
Attaching your DNA results helps others find your family tree through DNA. Furthermore, attaching and propagating your results will help others find and confirm a connection to your family tree. Ancestry.com family trees already contain uploaded family photographs, stories and other media files, historical documents, ancestor life timelines and now DNA! With 8.3 million family trees containing 810 million profiles, adding DNA results to a family tree multiples your chance of finding and making connections with genetic cousins and extending branches along your family tree. And as more people add their results, the Ancestry.com DNA database becomes a powerful asset toward making connections and family tree discoveries.


How can I tell if my DNA is attached to my name by DNA and not name based.
I am a result of an affair. I am trying to use my DNA to search for my paternal side by DNA and not name.
