In this training, we look at a great way to extend your DNA comparison database in a very useful (and free) manner using the GEDMatch.com service. Many of our Green Room Members already use this service, so I want to use this training to trigger your questions, discoveries and comments whether you are an old hand with this service OR just coming across it for the first time.
NOTE: Since I originally published this training in February, 2016 – many good things have happened:
- John Grenham ended his association with The Irish Times and moved his website location. We then we came to an arrangement with John that all Green Room members would have full free access to his site while they remained Green Room members.
- To claim your free membership of what is now called JohnGrenham.com – just go here and follow the instructions
- Finally, I have just changed the references in a minimal manner below – but will add more substantive changes over the coming weeks and months.
