HBCruiseHeritage Books, a leader in the world of genealogy publication for four decades, announces the 2nd Annual Heritage Books Genealogy Conference and Cruise, departing from Ft. Lauderdale, Florida on October 18, 2015 and returning on October 28th!

Interested in DNA?

This year’s cruise is focused on using the newest tool for your genealogical research, DNA testing. Are you a DNA newbie? No problem, with more than 20 different genetic genealogy presentations, this conference will take you all the way from complete novice to an intermediate user ready to add DNA to your genealogy toolbox. Are you well-versed in genetic genealogy? Come and learn the latest tips and tricks to enhance your DNA knowledge.

In addition to a full slate of presentations, one-on-one consultations, and several group sessions, conference attendees and passengers will have plenty of time to enjoy the sights, sounds, and flavors of the Caribbean as the Coral Princess makes stops in the topical destinations of Aruba, Cartagena, Grand Cayman, and even makes a partial transit of the unparalleled Panama Canal. You can find the full schedule for this amazing trip here.

Are There Any Absolutes in Genetic Genealogy?

I’ve recently noted a trend among genealogists to discount unexpected (or unwanted?) DNA test results in order to make the results fit an existing hypothesis, instead of properly re-evaluating the hypothesis in light of the new DNA evidence. (This is NOT made in reference to any specific person, post, or question; it is rather something I’ve been mulling over for some time).

Let’s take third cousins as an example. According to Family Tree DNA’s FAQ, you will share detectable DNA with approximately 90% of your third cousins under FTDNA’s threshold. According to AncestryDNA’s help page (see “Should other family members get tested?”), you will share detectable DNA with 98% of your third cousins under AncestryDNA’s threshold. In other words, if you have 100 third cousins and they all get tested (how’d you do that?), you will share DNA with 98 of them.

Collecting Sharing Information for Known Relationships – Part II

As you might recall, a few weeks ago I sent out a call for information about the amount of DNA shared by people having a known genealogical relationship. I was hoping to get a better picture of the ranges of the amount of DNA shared by people in these relationships (through about the third cousin range). Although people like Tim Janzen have gathered this type of data and so kindly made it available for everyone, I felt like more data was needed.

What is the range of cMs shared by third cousins? What does the distribution within that range look like? Does the longest segment factor into that at all? If so, how?

These are the types of questions I wanted to examine. And to entice submissions, I offered a free Family Finder kit to one lucky person that submitted data prior to April 1, 2015.
