Surveying Ancestry using Autosomal DNA Results

1. Surveying Ancestry using Autosomal DNA Results Matt Dexter @mkdexter Family Tree DNA International Conference 2015

2. To Survey • To View • To Line Up • To Plot Out • To Map

3. A Survey of Ancestry • Parent/Child Shares • Sibling/Cousin Shares • Inclusive Shares by Association • Exclusive Shares with Probability • Example

4. Sharing my Observations • 24 family finder tests (or transfers) • 5 grandchildren (cousins) • 6 grandparents • 4 great grandparents • And more
