Current happenings in the world of DNA and genealogy

First, now is the time to order a DNA test from It's $79 through July 4th.

Second, and are both offering new ways to combine DNA results with genealogy. The Geni system is designed to work with Family Tree DNA Family Finder, Y-DNA and mtDNA test results, a unique approach, although Wikitree offers something similar... and for FREE. MyHeritage is accepting DNA uploads but hasn't launched its matching service yet. I'm sure that will come soon. One shortcoming, at least for now, is that they will deal only with autosomal DNA, not Y-DNA and mtDNA..

Wikitree, Gedmatch... and why you should use them

If you haven't discovered yet, you really ought to take a look. It is building a universal tree like other wikis, but it has some unique aspects that add real value. For example, if you record your own DNA test information, it offers some of the coolest DNA-related features that are not available anywhere else. It will add the appropriate DNA links to your ancestors and descendants and provide reports showing your X-DNA, Y-DNA, mtDNA, and atDNA ancestors and descendants. It now also provides the ability to find others who have tested specific surnames. You can then compare their test results to your own. For anyone who is serious about proving (or disproving) their family tree, DNA testing and building triangulated groups is essential. Wikitree provides some amazing tools.

Of course, as always, is the essential site that offers the ability to do actual triangulation -- and it's free for most features. If you're concerned about privacy, simply use an alias and a separate email address, easily acquired free through Gmail and Yahoo.

AncestryDNA changes has made significant changes to its algorithms for matching. This link will take you to an excellent review of these changes and what they mean for all of us who have done or will do autosomal DNA testing with them.

The overall experience of current users is positive, although most of us recognize that no matching algorithm is perfect. There will always be some degree of false positive and false negative calls. Each company -- 23andMe, Ancestry and FamilyTreeDNA -- has its own proprietary system for matching. As always, it is wise to upload one's raw results from any ofthese three companies to where you can manipulate threshholds to evaluate different settings, matches and probabilities.
