To summarize, 23andme is a great company and for an advanced genetic genealogist who knows how to use a chromosome browser and figure out who people are even when they don't have a pedigree and don't respond to emails. A test taker without those skills and who lacks the time and effort to obtain them will likely make little headway trying to solve brick wall ancestors. Those who are looking for closer relatives such adoptees or those who have given children up for adoption, should definitely test with 23andme just in case the one close relative you are looking for has already tested in their database. Maybe your biological mother is in 23andme but not any other company. | To summarize, 23andme is a great company and for an advanced genetic genealogist who knows how to use a chromosome browser and figure out who people are even when they don't have a pedigree and don't respond to emails.

== Ancestry == | |||
Ancestry was founded in 1996 and has been selling DNA tests since 2012. They are based in Lehi, Utah. They sell Ancestry kits for $99 and Ancestry plus traits for $109. Often you can also add a three month membership to Ancestry's record database for $1 when you purchase a kit through them. | |||
The biggest advantage to AncestryDNA is their database. As of November 2018, they have sold over 18 million DNA kits. The sheer size of their database makes it more likely that you will find a genetic relative of interest to your problem. The other major advantage to Ancestry is the ability to link your DNA and pedigree together. You can upload your tree, link your DNA to yourself in the tree and then Ancestry will start comparing your tree against all your genetic relatives who also have linked their trees to their DNA. Not everyone has done this and many users have both DNA and a tree, but have not linked the two. | |||
Another major strength is their Thrulines feature. After Ancestry has compared your tree and tried to find as many genetic connections as possible, Ancestry will allow you to see all of these possible connections using Thrulines. Thrulines allows you to click on an Ancestor, and then it shows you all the other matches it thinks descends from that Ancestor and their relationships. It can even use their massive database of online trees to fill in some of the gaps when a match of interest only has a partial tree. One important thing to know about Thrulines is that it does not "go through the DNA" despite what many people seem to think. The formulas is simple, if two people share DNA their trees are sought for a common ancestor, but the DNA still needs to be analyzed to make sure that Thrulines found the right common ancestor. For example, Tanner Tolman has a match that according to the paper trail should be related on his grandmother's side. However, there was a non-paternal event and this particular individual is actually genetically related on his grandfather's side. This is obvious when looking at the shared matches, but Thrulines incorrectly assumes the relationship is on grandmother's side. In other words, Thrulines is great, but do not accept it without verifying the conclusions. | |||
The biggest disadvantage to Ancestry is their strict privacy rules. They do not have a chromosome browser, they do not have an auto cluster tool, and although they let you see people who share DNA with both you and another genetic match, they do not let you see how closely those shared matches are related to the other person. This can make things difficult when trying to construct a hypothetical tree or when people do not respond to emails asking for more information (which happens frequently). Many people in Ancestry's large database, bought the test, looked at their ethnicity results once, and then never logged in again. Also, to get the full value out of your AncestryDNA test, you will need a membership to Ancestry. Otherwise, you will not be allowed to look at the trees uploaded by your matches. | |||
In summary, Ancestry has strict privacy rules which can be irritating for advanced genealogists and those interested in chromosome mapping, Thrulines is not perfect, and many matches do not respond to emails which is especially hard for beginning genealogists. However, the size of their database really does make up for a lot. Many genealogists still consider Ancestry to be the best company for genetic research, especially if those researchers are working on brick wall Ancestors who lived in the United States. | |||
