Unlocking Family Secrets with the ADSHEAD DNA Project

The ADSHEAD DNA Project aims to enhance genealogical research through DNA analysis. By examining the Y chromosome, we can trace direct male lineage and identify historical familial groups with greater accuracy due to the low variability of the Y chromosome. Each individual's DNA presents unique differences, approximately every 1,000 bases. Combining DNA testing with traditional genealogy allows us to support or disprove connections between families. Join the discussion on the relevance of this innovative project for uncovering your ancestry and its historical context.

  1. The ADSHEAD DNA Project What can it do for us ?

  2. DNA Summary • Some Issues • Some Possible Targets • Quick look at a bit of Technology

  3. 3,000,000,000 bases long

  4. 51 Sally

  5. What can the Y chromosome tell you ? • Direct male line followed • Little variation so can be used to identify historical groups • Taking haplogroups together – genes arranged on a single chromosome – gives more detail / accuracy

  6. Variation between people • Your DNA is not identical to the next person • DNA differs approx every 1000 bases between people (0.1%) • As 3 x 109 bases – 3 x 106 differences • New variation is called mutation/variant • happens 1 / 10-9 per site per generation

  7. Relevance of DNA to Genealogy

  8. Creer Genealogy 1200 1300 ? 1400 1500 ? ? ? ? ? ? ? 1600 1700 1800 1900 2000

  10. DGS - DIDP Genetic Family A

  11. DGS - DIDP Genetic Family D

  12. Time to the Most RecentCommon Ancestor • Typical FTDNATip Report

  13. Conventional Research • Do the participants in question share a common ancestor? • How complete are their paper trails? • Are there any inconsistencies in their paper trails?

  14. Putting It All Together • DNA testing can be a valuable tool in genealogical research when combined with conventional research • Test results can be used to support a suspected connection between two families or disprove a connection • Although it is impossible to pinpoint a common ancestor from the test results alone, with a proper paper trail you may be able to do so

  15. Some Possible Targets • Registered an ADSHEAD DNA Study with Family Tree DNA – 3 years ago • Waited to get a lot more documentary evidence • What is “general” signature of ADSHEADs ? • Compare Different branches • Are we related to ADSHADE’s ? • Are we related to ADSET(T)(E)’s ?

  16. Some Issues • PRICE: 40 / 80 / 120 $ - set up fund • Men Only • “Non-Paternity” • Security Policy - some good guidelines • RISKS Eg. Australian story & Lodger story

  17. Any Interest
