Genetic Genealogy News
My search for descendants of David Cannady of Livingston county and McCracken county in Kentucky begins with looking at the records for him in the federal census. This search is a key part in my 2018 goals for Big Y DNA testing and the CANADA surname branch of my family.
One of the most important truths of genetic genealogy is that successes do not happen on their own. Genealogists plan them. Unless you are adopted or have an unknown paternity on your paternal line, the best practice for Y-chromosome DNA genealogy is testing of targeted people combined with traditional genealogy.
On the 11th, I put together a Facebook group for Y-DNA, then I held off on pushing it live. I was not 100% sure what direction I wanted it to take. While waiting, I have discovered two things. First, the genetic genealogy community is ready to embrace NexGen type Y-DNA testing like Family Tree DNA's Big Y. Second, more than ever, new and even experienced community members are confused about what Y-DNA testing can do for their genealogy and the meaning of the jargon.

The Non-recombining region of the Y-chromosome (NRY) is transferred from father to son in an unchanged form without recombination in meiosis. Since Short tandem repeats on Y-chromosome (Y-STRs) in this region do not have any recombination, these regions are identical in all male individuals who are related to the father except for mutations.
The black legend on the Spanish presence in the low countries: Verifying shared beliefs on genetic ancestry
War atrocities committed by the Spanish army in the Low Countries during the 16th century are so ingrained in the collective memory of Belgian and Dutch societies that they generally assume a signature of this history to be present in their genetic ancestry. Historians claim this assumption is a consequence of the so-called “Black Legend” and…
Differences in genetic structure assessed using Y‐chromosome and mitochondrial DNA markers do not shape the contributions to diversity in African sires
Up to 173 African sires belonging to 11 different subpopulations representative of four cattle groups were analysed for six Y-specific microsatellite loci and a mitochondrial DNA fragment.
Haplotype diversity of 17 Y-chromosome STR loci in Han population from different areas of Sichuan Province, Southwest China
The distribution of 17 Y-chromosome short tandem repeat (STR) loci, included in the AmpFlSTR®Yfiler™ amplification kit, were analyzed in six different samplings (N = 878) from Sichuan, China.
