Not so long ago, my computer backup plan against various calamities looked something like this:
- Against flood: keep my laptop off the floor.
- Against fire: grab my laptop in one hand and my youngest child in the other.
- Against theft: hide my laptop under a different pile of blankets every time I leave the house.
No lie, this was my plan. You don’t have to tell me how terrible it was.
Fortunately, I’ve improved somewhat. I stash copies of important files in Dropbox. Older photos and files are backed up online and on an external hard drive. I started using cloud-based email.
But last week my laptop got sick. First it ran a fever, then shut down entirely. My computer repairman, usually an optimist, said, “Please tell me you have everything backed up.” I hesitated. He sighed.
That crash took three days to resolve and resulted in a prescription for a cooling fan and the dire news that my laptop is living on borrowed time. I was sternly instructed to back everything up, because in those three days I had discovered considerable gaps in my backup plan.
Fortunately, Lisa had just announced buy pain medication online legally Genealogy Gems’ new partnership with Backblaze. I figured if Lisa could entrust thousands of audio, video, image, text, communication and other files to them, I could do the same. So….I signed up for Blackblaze. It’s $5 a month ($50 a year). Less than I spend on Redbox movies for my kids.
It’s taken Backblaze a few days to process my initial backup of over 120,000 files. It’s running continuously in the background and will continue to do so as I work. Like a little data butler, waiting to tidy up after me and be there for me when I need it. Backblaze will even backup my external drives, too (“no extra charge, madam”).
It’s so comforting to have Backblaze that I’ve stopped hiding my laptop under blankets when I leave the house. Because I was still doing that.
If your backup plan needs a little help like mine did, consider Backblaze. It’s easy to sign up, it’s comprehensive and it’s just a few dollars a month. Click here to check it out: www.Backblaze.com/Lisa. Whatever your backup strategy, watch our blog for more on disaster planning and prevention.

In the last year I’ve moved from Earthquake Central (California) to Tornado Alley (Texas) and it’s been a bit of an adjustment, to say the least! Recently I presented a live webinar on using Evernote for genealogy during a tornado watch, with my husband fretting in the background. Not long after, we spent an hour in our shelter room during torrential rains, non-stop lightning, and nearby tornado touchdowns.
All this threat of danger and destruction has reinforced my decision to bring into our Genealogy Gems family a brand new sponsor. Backblaze is now the official back up of Lisa Louise Cooke’s Genealogy Gems. Backblaze isn’t new to the genealogy space: if you’ve been to RootsTech, you’ve likely seen their booth. Backblaze is a trusted online cloud backup service that truly makes backing up all your most precious computer files super easy.
Many of you have asked me which company I use to back up my files. I’ve done my homework and Backblaze is my choice. The thought of losing my genealogy files is too much to bear. Now I can concentrate on keeping my loved ones safe through the storms of life because I know Backblaze is taking care of my files and photos! A few things to consider:
- They back up ALL your files (or just those you select). Music, photos, data, documents, etc.
- You have an unlimited amount of data storage on Backblaze.
- In the event you lose data, you can download from any computer or have a hard drive FedExed to you.
- For the price of a single average hard drive restoration (when it’s even possible), Backblaze could back up your computer for 50 years.
- External drives are great, but if they’re sitting next to your computer, they would be lost in a natural disaster, too.
- Backblaze serves both Mac and PC owners.
- You can get started for free. And then it’s really inexpensive to have them continuously back you up. Only $5 per month, last we checked, or $50 for an entire year.
I invite you to visit www.Backblaze.com/Lisa and get all your files backed up once and for all!

Are your DNA ethnicity results exciting, confusing, inconsistent, exasperating…or all of the above?
Recently Kate expressed on the Genealogy Gems Facebook page her frustration with her ethnicity results provided by AncestryDNA. She gets right to the point when she writes, “the way they refer to the results is confusing.”
Kate, you are not alone. Many genealogists have been lured into taking the autosomal DNA test at one of the three major DNA testing companies just to get this glimpse into their past. Remember that the autosomal DNA test can reveal information about both your mother’s side and your father’s side of your family tree. Many take the test hoping for confirmation of a particular ancestral heritage, others are just curious to see what the results will show. Though their purposes in initiating the testing may vary, the feeling of bewilderment and befuddlement upon receiving the results is fairly universal.
Kate has some specific questions about her results that I think most will share. Let’s take a look at a couple of them. First up, Kate wants to know if our family tree data in any way influences the ethnicity results provided. The answer is an unequivocal “no.” None of the testing companies look at your family tree in any way when determining your ethnicity results. However, the results are dependent on the family trees of the reference population. The reference populations are large numbers of people whose DNA has been tested and THEIR family history has been documented for many generations in that region. The testing companies compare your DNA to theirs and that’s how they assign you to an ethnicity (and place of ancestral origin?).
Next Kate asks, “Do they mean England when they report Great Britain?” Or to put it more broadly, how do these testing companies decide to divide up the world? All of the companies handle this a little bit differently. Let’s look at Ancestry as an example. When you login to view your ethnicity results, you can click on the “show all regions” box below your results to get a list of all of the possible categories that your DNA could be placed in. These 26 categories include nine African regions, Native American, three Asian regions, eight European regions, two Pacific Island regions, two West Asian regions, and then Jewish, which is not a region, per se, but a genetically distinct group.
Clicking on each individual location in the left sidebar will bring up more information on the right about that region. For example, clicking on Great Britain tells us that DNA associated with this region is primarily found in England, Scotland, and Wales, but is also found in Ireland, France, Germany, Denmark, Belgium, Netherlands, Switzerland, Austria, and Italy. Basically, this is telling us that people with generations of ancestry in Great Britain are quite a genetic mix from many areas.
The first chart here shows that if we are to test the DNA of 100 natives of one of these primary regions (England, Scotland or Wales) then 50 of them willhave the great Britain “pattern” of DNA covering 60% or more of their entire genome, and 50 of them will have that pattern in less than 60% of their DNA. The fact that this half-way number is so low, only 60%, tells us that there is a lot of uncertainty in this ethnicity estimate because there is so much mixture in this region. Kate, for you that means that when you see Great Britain in your ethnicity estimate, it could mean England, or maybe it means Italy- Ancestry can’t be certain.
But that uncertainty isn’t the same for every region. Pictured here is also the ethnicity chart for Ireland. You can see that half the people who are native to Ireland will have 95% or more Irish DNA. Kate, for us this means that if you have Irish DNA in your results, you can be pretty certain it came from Ireland. From these tables you can see your membership in some regions is more robust than others, and Ancestry is using these tables to try to help us tell the difference.
In the end, the ethnicity results reported by each DNA testing company are highly dependent on two factors: the reference populations they use to compare your DNA against, and the statistical algorithms they use to compute your similarities to these populations. Every company is doing both of these things just a little bit differently.
Kate, if you want to get another take on your ethnicity results, you can take your data over to Family Tree DNA, or you can be tested at 23andMe. A free option is to head over to Gedmatch and try out their various ethnicity tools. If you need help downloading and transferring, you can head over to my website: http://www.yourdnaguide.com/transferring. Most people have found after searching in multiple places that their “true” results are probably somewhere in the middle.
While these ethnicity results can be interesting and useful, for most they will just be a novelty; something interesting and exciting. I have found that their most useful application is acting like a fly on a fishing line. They attract our family members into DNA testing where we can then set the hook on the real goal: family history.
If you’re ready to bait your own hook, I recommend you check out my series of DNA quick guides. These guides will help you choose the right DNA tests for your genetic genealogy questions. You’ll become a smart shopper, more prepared to choose the testing company that’s right for you. And you’ll be prepared to maximize your results from each company, rather than look at them blankly and wondered what the heck you just spent that money on.

The genetic genealogy community has a crush. A big one. Everyone is talking about it. “It has such great features,” says one. “It has a chromosome browser!” exclaims another. “It’s FREE!” they all shout. What’s all the hype about? GEDmatch.
GEDmatch is a mostly free online tool where anyone with autosomal DNA test results from 23andMe, FTDNA, and AncestryDNA can meet and share information. All you need to do is download your data from your testing company and upload it into your newly created GEDmatch account.
GEDmatch Set-up
Gedmatch Find Matches
GEDmatch is set up just like your testing company and provides two kinds of reports: ethnicity results and a match list. Remember, ethnicity results, meaning those pie charts that report you are 15% Italian and 32% Irish, are based on two factors: a reference population and fancy math. GEDmatch has gathered data from multiple academic sources to provide you with several different iterations of ethnicity reports. This is like getting a second (and third and fourth, etc) opinion on a science that is still emerging. It is a fun exercise, but will likely not impact your genealogy research very much.
The more important match list does allow you to see genetic cousins who have tested at other companies. Of course, only those who have downloaded their results and entered them into GEDmatch will show up on your list. This means GEDmatch has the potential to expand your pool of genetic cousins, increasing your chances of finding someone to help you track down that missing ancestor.
Many also flock to GEDmatch because they were tested at AncestryDNA and so do not have access to a chromosome browser. A chromosome browser allows you to visualize the physical locations that you share with someone else (see below). Some find this a helpful tool when analyzing their DNA matches, though in my opinion, it is not essential.
Example
GEDmatch also has some great genealogy features that let you analyze your pedigree against someone else’s, as well as the ability to search all the pedigree charts in their system so you can look specifically for a descendant of a particular relative. However, even with all of these great features, GEDmatch is still yet another website you have to navigate. With that, there will be a learning curve and certainly some frustration.
GEDMatch or Not?
So, is it worth it? If you are fairly comfortable with the website where you were tested, and you are feeling both curious and patient, I say go for it!
It’s too much to tell you right this minute how to download your data from your testing site and upload it to GEDmatch, but you’re in luck! I’ve put step-by-step instructions for getting started in a free tutorial on my website at www.yourDNAguide.com/transferring.
