  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

  9. Creer Genealogy + Y-DNA Analysis 1200 “Ancestral Creer” 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
