This might be the single most ambitious publication EVER: a chart that lays out the history of human civilization. It’s the ultimate infographic, created long before the era of the infographic!
What you see here is a partial image, a screenshot taken from a cool article on the 1931 Histomap: Four Thousand Years of World History.
It’s not perfectly accurate, it carries some cultural biases and ignorance of much of Africa’s rich history and the dates are given more as a range than anything. So what makes this a useful tool for genealogists?
We’re always looking for historical context: a way to understand how our ancestors fit into the “big picture” of history. Are you learning about a Portuguese or French line in your family? Learning by DNA tests that you have some deep Asian roots? Find these categories displayed on the map along with other dominant (or not-so-dominant) groups of your ancestor’s era. It’s cool to look at! Check out the entire map (and an explanatory post in this post by Rebecca Onion at Slate.com.
Genealogy Gems Contributing Editor Sunny Morton owns a book with a similar chart in it: Timechart History of the World (Timechart series)
The Timechart History of the World. The oversize, double-sided stiff cardboard pages fold out to more than 30 feet of full-color Victorian-decorated timecharts. She highly recommends it for the coffee table, if your coffee table is big enough to handle it!
Bonus: The Huffington Post has a neat article (with a photo) of another map from this series,The Histomap of Religion. (Time Chart of World Religion: A Histomap of Faith Through the Ages
) Religions can be tough to trace forward over time, as various sects divide or merge. Every tool helps!

Ancestry.com has improved the ability of AncestryDNA to find good matches for Jewish, Hispanic and other ancestries that maybe weren’t so precise before. Here’s the lowdown, quoted liberally from Ancestry.com’s press release:
The problem: Predicting genetic relatives among customers of Jewish and Hispanic descent and some other groups. “In DNA matching, we are looking for pieces of DNA that appear identical between individuals,” says the release. “For genealogy research we’re interested in DNA that’s identical because we’re both descended from a recent common ancestor. We call this identical by descent (IBD). This is what helps us to make new discoveries in finding new relatives, new ancestors, and collaborating on our research.”
“However, we also find pieces of DNA that are identical for another reason. At one extreme we find pieces of DNA that are identical because it is essential for human survival. At the other, we find pieces of DNA that are identical because two people are of the same ethnicity. We call these segments identical by state (IBS) because the piece of DNA is identical for a reason other than a recent common ancestor. This, we have found, often happens in individuals of Jewish descent.”
“The challenge in DNA matching is to tease apart which segments are IBD, and which ones are IBS….Most Jewish customers find that we predict them to be related to nearly every other Jewish customer in the database….Detecting which cousin matches were real and which ones were bogus has always been a challenge for these populations.”
First step toward a solution: “By studying patterns of matches across our more than half a million AncestryDNA customers, we found that in certain places of the genome, thousands of people were being estimated to share DNA with one another–likely a hallmark of a common ethnicity. Our scientific advancements… have allowed us to effectively “pan for gold” in our matches–by throwing out matches that appear to only be IBS, and keeping those that are IBD.”
“While the problem was more pronounced in customers of Jewish and some Hispanic descents, we observed this problem across all ethnic groups. So, all customers will see increased accuracy of their DNA matches, and significantly fewer ‘false’ matches.”
AncestryDNA results with better matches found by this method “will be available in the coming months,” says the release. They plan to email existing customers when results are ready.

Recently my Premium Podcast included a letter from Pat, who was looking for advice on how to return lost or orphaned heirlooms to a family. Ancestry.com had a few family trees posted. Pat didn’t know “whom to contact to get the materials to the most interested, closest family members.” This was my advice–and here’s the inspirational report back.
My advice:
I would first focus on the tree where the tree owner is most closely related to the folks mentioned in the memorabilia. I would probably make copies (depending on what the items are) and offer to all. If I didn’t get a confirmed answer from the first choice in a reasonable time I would offer to my second choice. I would ask the recipient to allow me to pass their contact info on to any others who get around to responding after the fact since it’s everyone’s “family”.
Pat’s response:
“I finally took up the challenge, determined to find a family and offer up the material I had recovered. This material contained old (labeled!) photos, school records, dance cards and letters home to Mom and Dad and seemed potentially quite precious.
It proved difficult to determine which family seemed to have the closest connection, so I decided to offer the material to the person whose Ancestry.com tree contained the most (valid) sources. Fortunately, the tree owner was quick to respond, eager to receive the materials I had to offer. I sent them off and the tree owner is delighted as she is the granddaughter to the original party and believes herself to be the only living descendant of that person!
It feels just right to get those materials back “home”! I encourage other listeners to do the same. It produces a great sense of genealogical balance. So many others have done blessedly wonderful things for me in my research, making it easy to pay it forward just a little bit.
Thank you for the encouragement and the advice. I have loved both podcasts for a number of years now–you are consistently wonderful!”
Thanks, Pat, both for the compliment and for the inspiring message! I love hearing these kinds of stories.
