  • Most have a help center or FAQ
  • Use the ISOGG wiki- https://isogg.org/wiki/
  • You can always Google any question you have

Your autosomal test data is about 700,000 lines of data in a spreadsheet so best to use tools to analyze it!

Most Americans are a blend of ancestries

 

Each company has a different way of calculating yours

None are perfect yet, but the general outlines are accurate

Clicking on a year gets this display, the numbers show how many ancestors there

How Does Ancestry Composition

Help My Genealogy?

When you get an unexpected result

There were rumors that the grandfather of my jewish friend was a local nobleman

Two Ashkenazi Jewish Friends, one with some Sephardic ancestors 

The ancestry composition at 23andme is under Reports > Ancestry

Only 23andme gives you maternal and paternal haplogroups. See http://www.eupedia.com/europe/origins_haplogroups_europe.shtml

The top of the page gives an overview

The timeline feature attempts to tell you when that ancestor was

If you have a parent tested, it will break out the ethnicity by parent

Newly found "DNA" cousins can help you with your genealogy

They may have family stories and photos you do not have

My 3rd 1R sent me photos of my gg-grandparents

FINDING  COUSINS

Do I really have to look through a thousand cousins?

NO!

Start with the low hanging fruit, 3rd cousins and closer

(100cM and larger)

Enter the cMs and get probable relationships https://dnapainter.com/tools/sharedcmv4

Cousin Matches

  1. How much shared DNA in centimorgans (cMs)?
  2. Who else do they match?
  3. How many segments? (More than 2 is best)

Getting New Cousins to Respond to You

  • Have a family tree online
  • Upload friendly picture of yourself
  • Include details of who matches whom (they may have multiple kits)
  • Offer them information when you write to them

Do not be disheartened by lack of responses, some rarely log in 

The top right corner of your Ancestry DNA page has some important icons

  • Be sure to click on the envelope with the blue number to read your messages
  • Be sure to connect your DNA test to your tree (click the gear icon, settings, to get to that page)

Use Family Tree Linking to connect your DNA results to your tree

Ancestry Tree "Green Leaf" Match

Clicking on View Match gets a page that may have a tree

Where is the 23andme Cousin Matching Page?

23andme Cousin Matches

Click through to a Match gets a long page with much information

The match page also

shows your population

break downs side by side

The match page shows a chromosome map of where the matching DNA is BUT no numbers here

At the bottom of the 23and me match everyone who matches both of you is listed and a YES indicates that there is overlapping DNA between these 3 people (automated triangulation)

Clicking that YES gets this, segment data (numbers) at bottom
