Beginning with DNAPainter

This session focuses on the free aspects of DNA Painter at http://www.dnapainter.com.

We will discuss downloading matching data from DNA sites, painting your DNA matches, finding match data, labeling, grouping, overlapping segments, and more as time allows. Our concentration is on getting you started with DNAPainter in a way that will help you make effective use of it as your research progresses. If you’ve wondered what DNAPainter is, how to use, and what it can do for you, this presentation will help you to do that. Ordering the presentation includes the recorded presentation (that can be viewed more than once) and a detailed handout as a PDF file.

You cannot upload your raw data to DNA Painter. You need the segment data that you can get from 23andme, FamilytreeDNA, Gedmatch, and MyHeritage.

Order the presentation and handout ($16.99) for immediate download.

Based upon suggestions from readers, we’ve put together this session on DNAPainter and GedMatch combined. Using just one tool is not an effective way to analyze your DNA matches.

Date: This session has been held and recorded.

  • order for immediate download for $17.99–presentation and PDF handout included
  • if you ordered early and did not receive download-email me (tell me the email used for payment) and I’ll send the download link.

From GedMatch, we’ll use:

  • one-to-many matches
  • one-to-one compare
  • matching segment search

DNAPainter’s mapping tool will be also be utilized. DNAPainter tells you when a new painted match has shared DNA with other matches you’ve already painted. We’ll be using that feature of the site.

We will look at:

  • organizing your analysis and process
  • documenting your thought process and conclusions for later review
  • tracking shared matches
  • assigning segments to ancestors and couples
  • specific examples–including one where the grandfather of the testee was unknown

What you should already know or have done:

  • Basics of DNA analysis–accuracy of predicted relationships, centimorgans and segments, why you don’t have DNA from every one of your ancestors, why third cousins may not share DNA, why siblings don’t have the same DNA, why predicted cousin relationships are estimates, etc.
  • Experimented with DNAPainter–at least painted a few matches.
  • Also recommended that you’ve already uploaded you DNA data to GedMatch–we won’t be discussing how to do that in this presentation.
  • Have already looked at your GedMatch results



Preparing for Your Autosomal DNA Results-Webinar

This hour-long presentation will present a brief overview of what autosomal DNA results are and are not. These are the tests that are done at AncestryDNA, MyHeritage, FamilyTreeDNA, and 23andMe. Effective use of your results is easiest to do if pre-planning is done beforehand. This presentation will also help those who have not really delved into their results or feel they need to regroup their analytical process.  Discussion will include determining what problems your results can potentially answer, goal-setting, preparing for sifting through your results, generalized sifting strategies, locating as many ancestral descendants as possible, reasons why you have to work on the people who aren’t your problem people, and more as time allows.

AncestryDNA Beginnings

This hour-long presentation covers the basics of working with DNA matches at AncestryDNA, including:

  • ethnicity estimate–briefly
  • communities–briefly
  • circles–briefly
  • matches

An overview of working with your matches, interpreting them, understanding them, analyzing them and organizing them is presented. Challenges of working with treeless matches, matches with incomplete trees, people who don’t respond, etc. are also discussed. This is a practical how-to session that also includes an overview of DNA and inheritance sufficient to work with the AnestryDNA results without being overwhelming. Comments included:

it was a very helpful overview and I appreciated the tips

Beginning Working with Your AncestryDNA Matches

This webinar focused solely on using, interpreting, and understanding AncestryDNA matches.

We will not discuss the ethnic “pie” on AncestryDNA and it is assumed attendees understand that siblings do not share all their DNA and may have different “ethnic percents” from each other.

The “Working With Your AncestryDNA Matches” session builds on my “AncestryDNA Beginnings” webinar. Those who have not worked with their DNA matches at Ancestry.com and are unfamiliar with DNA results may benefit from viewing that presentation.

We will see in “Working With Your AncestryDNA Matches” how to download the matches so your work with them can be tracked and analyzed, preventing “going in circles” when using your matches,” how to develop strategies to figure out “how matches are related” (as best as can be done), how to download your actual DNA data so that it can be uploaded to other sites, problem-solving with the DNA matches, and more (within hour long time frame). Practical examples will be demonstrated. We will be technical enough to explain things but not so much as to overwhelm.


Sifting Through Your AncestryDNA Matches–Followup to “Working with AncestryDNA Matches”

This session assumes listeners/attendees have a basic understanding of what AncestryDNA offers, how to navigate their AncestryDNA matches, how to track working with their matches, what shared matches are and are not, and have already done some work with with their AncestryDNA matches–at least having worked through their first/second cousins matches at least once to determine connections where possible. If you have not yet played with your matches, this session is not for you. The basics of the system are not covered in this session. This is a session focused on research methodology and more advanced working through the matches.

In this session we will work through several extended examples based on Michael’s own research. This will include a relatively straightforward example,  families that have multiple relationships, and families from areas where “they’ve lived there for hundreds of years” and the shared relationships are distant and unknown. The importance of sifting out (where possible) and tracking will be emphasized. Our focus is on process and analysis–not in making you a geneticist. 


GedMatch.com Webinar 1

I’ve just finished my first webinar on Using GedMatch.com to analyze your DNA results. This is a recorded copy of the presentation.

Discussion included:

  • overview of GedMatch
  • why you should use GedMatch
  • basic GedMatch DNA analysis tools-free ones only
  • one-to-many matches
  • one-to-one compare
  • matching 1 or 2 tests
  • downloading reports
  • matrix comparisons
  • segment matrix

Basic DNA terminology is not a part of this presentation. Focus is on being practical–presentation is down-to-earth and easy to understand.

GedMatch.com Webinar 2–the Tier 1 Functions

Tier 1 Options on GedMatch

This presentation will focus on an overview of the Tier 1 search options of GedMatch. Tier 1 is the “fee-based” part of GedMatch–it costs $10 a month and helps support the free portions of the site. GedMatch allows you to “see more” of your DNA and analyze it in ways that simply are not possible on AncestryDNA and some of the other sites.

We will look at the:

  • One-to-many matches
  • Matching segment search
  • Relationship Tree Projection
  • Lazarus
  • Triangulation

Our focus will be on interpreting the results and using them for continuing your genealogical research. A basic understanding of DNA is required. You do not need to be a “Tier 1” member of GedMatch to participate. Our approach is practical, easy-to-understand, and engaging.

The grid shows the “matching segment search.”

ThruLines(TM) At Ancestry.com

Now available for immediate download!

We’re excited to offer an hour-long presentation on the new ThruLines(TM) functionality at AncestryDNA. This functionality makes it easier to organize and sort some of your DNA matches at AncestryDNA. The session was held on 17 March 2018 and includes:

  • understanding  where the information in the tree comes from–what’s yours and what’s someone else’s;
  • basics of evaluating the information in the tree;
  • responsibly using ThruLines(TM) information;
  • limitations of ThruLines(TM)
  • basics of how much DNA you typically share with certain cousins and relationship prediction;
  • do you really have the right genealogical connection with that DNA match;
  • using ThruLines(TM) to sort your matches with linked trees;
  • problem-solving and trouble shooting with ThruLines(TM).

Our focus is on:

  • being practical, hands-on, and easy-to-understand;
  • not getting overly excited about using ThruLines(TM);
  • employing sound genealogy methodology.
