Is the tail wagging the dog in your genealogy research? Resist the temptation to jump at each hint and online family tree. Instead, take the lead in your own research and follow the scent of each clue with genealogical best practices. Here’s how…

Almost as soon as you start adding information to your family tree on any of the major genealogy records sites (Ancestry, MyHeritage, Findmypast) you will start getting suggestions. These suggestions are known by a variety of names on the various sites, such as hints, Shaky Leaves, Smart Matches, record matches, etc. No matter what they’re called, they can be a great way to quickly make even more progress in growing your family tree.

There’s an old saying: you get what you pay for. In the case of hints, you have technically paid for them by subscribing to the genealogy website’s service. However, you didn’t pay for them through careful research following solid genealogical methodology. You haven’t yet verified their accuracy, or in the case of suggested online family tree, verified their sources.

Online family trees are one of the most common types of hints you’ll receive. And it’s no wonder: there are billions of names entered in online family trees*, so your tree is very likely to match some of them.

However, with all those matching trees there are bound to be problems. If you’ve been wondering about the reliability and usability of other people’s online family trees being recommended as hints, you’re not alone. Keep reading to learn more about using information gleaned from other’s online family trees.


Brenda is a Premium eLearning member, and she wrote me recently with a question about using online family trees:
“I’m just getting back into my genealogy research after 10 years of not having time. It seems that research has completely changed to online work! I’m getting [hints that link to other] family lines, but can I trust them?”

And this related question comes from Douglas: “Weekly, I get emails with family tree matches, asking me to confirm the match. My problem is not with the matching but with when I dig into their tree, the source for their information is another tree. That info may be a clue but I learned way back that the info needed to be backed up by good primary and sometimes secondary sources, not what somebody thought was right.  Info that I entered in my tree years ago and found subsequently to be wrong is still hanging out in a dozen trees. What is your opinion?”

My guess is that at some point you’ve had some of the same questions as Brenda and Douglas. Am I right? Well, even though it’s exciting to find someone who’s already built a family tree that includes your ancestors, it’s important to proceed with caution. Avoid the temptation to “graft” or copy the tree onto your tree. That’s not to say you should ignore online trees. Instead, let’s discuss how reliable they are and how to use them wisely and responsibly.


Douglas has stated the problem accurately. The researchers behind those tantalizing trees may have made mistakes or copied unfounded information without verifying it. Unfortunately, this is a very common occurrence. Once copied to one tree, incorrect information can easily get picked up by others and copied over and over again. And the problem is made worse because the more it’s copied, the more unskilled researchers may assume it must be accurate because they see everyone using it. It’s a vicious circle indeed!
