David Cannady in the U.S. Federal Census

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.

Y-DNA Testing Strategy – Case 1, the Kennedy-Cannaday-Canada Family of Western Kentucky

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.

Announcing the Y-DNA – Applied Genealogy & Paternal Origins Facebook Group

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.

Y-DNA Trees and How They Grow

We just covered how the Y Chromosome Consortium formed and in 2002 published a united tree for the paternal Y-chromosome tree. The other thing they outlined in their 2002 paper was the ways the tree can change over time. Today's post will go over these.

Estimation of the Y-chromosomal short tandem repeat (Y-STR) mutation rates in Turkey

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.
