My family’s eyes glazed over when I mentioned enthusiastically at Thanksgiving dinner that I was reading a great book about the history of doing family history. So I did not go on to tell them all the ways The Invisible History of the Human Race: How DNA and History Shape Our Identities and Our Futures by Christine Kenneally discusses how DNA, family history, and culture affect who we are.

I was fascinated by the discussion of the cultural lack of trust even today in some West African countries where selling people off to slavery was a possibility a few hundred years back. Or the silence about the past in Tasmania where almost all the founding population was made up of convicts. Or the genetic research into who the Melungeons really were.

This book wanders over many family history, DNA, and related topics but it does it so very well. She starts with discoveries about her own family and moves out from there.

Like many books that I find enjoyable, I read it far too fast (in three days) so now I am going back through it more slowly.

A great Christmas gift for the genealogist in your family.

All my favorite bloggers have posted good articles about the changes in the Ancestry.com DNA pages. I have put a list of them at the end of this post.

The improvement in Ancestry’s DNA matching has greatly reduced the total number of matches, which ran into the thousands for many of us. The theory is that their new algorithm has gotten rid of those matches that were unlikely to share a common ancestor in the genealogical time frame. I am hopeful. And the new DNA home page for a person is much nicer looking and more informative as you can see below.

Looking at how my brother with one Jewish grandparent has fared, all his 4^th cousin Jewish matches (dozens of those) are gone. This is probably correct. The few that I have been in contact with are not recently related.
