Deep Analysis Tools for Genetic Genealogy

These are third party tools for in depth analysis of your raw DNA data. Be sure that you have a solid understanding of everything in the Intro videos before using these tools. Not interested in deep analysis? That’s ok. smiley

If you are not interested in doing the deep analysis yourself, please consider uploading your raw data to then sharing your Gedmatch ID through places like your family reunion Facebook pages. Someone in your family is likely to be interested in doing the deep analysis and your DNA data might be THE one that solves a family genealogical mystery.


GENEALOGY TOOLS (FREE, but consider donating if you find the tool useful)

The starting point for deep analysis is uploading your raw Ancestry DNA data to Register with a free account and follow their instructions on how to download your DNA data from and then upload to Gedmatch. Within a few days you will find that you have a whole slew of new matches with people who tested with the other major testing companies!

Ancestry DNA’s hints on how we connect to our DNA cousins are wonderful, but they only tell us a suggested level of match (2nd cousin, 4th to 6th cousin, etc.). A chromosome browser is required to tell you exactly what segment of what chromosome you actually match on. is a free website with a chromosome browser and some other comparison tools and tools for looking at ancestral origins (what countries did my ancestors come from?). Why use a chromosome browser? To figure out exactly how we connect and to find new cousins using DNA! This cartoon explains it pretty well. (FREE, but consider donating if you find the tool useful)

The tools and documents at DNAgedcom were developed primarily for the use of Adoptees looking for birth family but are not limited to that purpose. Their tools enable lining up of DNA data to find the overlapping DNA segments that match each other. People in these groupings are likely to have a common ancestor. The dedicated researcher can then extract actual familial relationships by finding the overlap in family trees of people who have significant regions of matching DNA. To learn more about DNAgedcom tools and about using DNA to figure out family relationships in general visit

A few times a year DNAgedcom offers a class on how to do DNA analysis to find familial relationships. Class size is limited and the suggested donation to take the class is $30.


Genome Mate (FREE, but consider donating if you find the tool useful)

Genome Mate is in my humble opinion amazeballs. What is Genome Mate? It is a database program specifically designed for genetic genealogy that lets you pull all of your genealogical DNA data and associated information together in one place. Besides data storage it has many features to aid in identifying common ancestors. One of the coolest features is the ability to map what part of your chromosomes were inherited from what ancestors.

Promethease ($5)

Promethease builds a personal DNA report from your DNA file based on known genetic associations of traits and susceptability to disease from the medical and scientific literature cited in SNPedia. If you have a specific gene (identified in these tests using snps – single nucleotide polymorphisms) associated with odds of getting some disease, in nearly all cases it doesn’t necesarily mean that you will get that disease. It just means that you have greater odds of developing the disease than someone who does not have that gene.
