Obsidian for Genealogists: The Note-Taking App That Might Change How You Research
A while back, I wrote a post comparing several mind mapping apps, and one name kept drawing my attention after I’d finished writing: Obsidian. I realized there is a lot to say about Obsidian for genealogists. I promised myself I’d take a closer look — and once I did, I fell down a rabbit hole I haven’t quite climbed out of.
Obsidian isn’t a mind mapping app, not really. It’s something broader and, for genealogists in particular, potentially more useful: a tool for building a web of linked notes that mirrors the way our research actually works. Add to that a huge library of community plugins, a completely free core product, and the fact that your data lives as plain text files on your own computer — and you have something worth a proper, in-depth look.
What Obsidian Actually Is
At its heart, Obsidian is a note-taking app built around plain Markdown files. Every note you write is saved as a simple .md text file sitting in a folder on your computer — no proprietary database, no cloud lock-in, nothing you can’t open in Notepad in twenty years’ time. That alone should catch a genealogist’s ear: we spend our lives worrying about the longevity of formats and the survival of records, and here’s a note-taking tool built on the most durable, boring, non-proprietary format there is. Obsidian also has strong time-management tools.
What makes it different from a plain folder of text files is linking. Inside any note, you can type [[Ola Hansen]] and Obsidian instantly creates a link to a note called “Ola Hansen” — creating it on the fly if it doesn’t exist yet. Do this enough times, across enough notes, and Obsidian builds something it calls the graph view: a visual web showing how every note connects to every other note.
For most users, this is handy for connecting ideas. For a genealogist, it’s something closer to a research management system in disguise.
Why This Matters for Genealogy Specifically
Genealogical research is, by nature, a tangle of connections. One person appears in a baptism record, a census, a probate document, a ship’s passenger list, and a letter from a second cousin — and understanding them means holding all of those threads in your head at once. Most of us end up doing this with a mix of spreadsheets, a genealogy program’s built-in notes field, sticky notes, and memory. Obsidian offers a different approach: let every person, place, source, and event live as its own note, and let the links do the remembering for you.
A few ways this plays out in practice:
A note per ancestor. Instead of a cramped notes field in your genealogy software, each ancestor gets a full page: what you know, what you suspect, what’s still missing, links to every source that mentions them, and links to every relative also documented in your vault. Click into a name and you see the whole tangle of connections radiating outward.
A note per source. Church books, censuses, probate records, emigration protocols — each becomes its own note with a citation, an image or transcription, and links to every person it mentions. This solves a very real genealogical headache: tracking which conclusions rest on which evidence, and revisiting a source instantly when new questions arise.
The graph view as a research map. Zoom out, and the graph view shows clusters — a farm, a parish, an emigrant ship — where names bunch together because they share sources and events. Isolated dots at the edges are often exactly where your brick walls live: people with too few connections to the rest of your research. I’ve found this more revealing than any pedigree chart for spotting where I’ve been neglecting a line.
Backlinks as a research trail. Every note shows you, automatically, every other note that links to it. Open a farm’s note and you instantly see every person who ever lived there, without having to remember to cross-reference it yourself.
The Plugin Ecosystem — Where Obsidian Really Opens Up
Obsidian’s core is intentionally minimal, but the community plugin library is where things get genuinely exciting for research work. A few that genealogists in particular will want to look at:
- Dataview — lets you write simple queries that pull information out of your notes automatically. Want a table of every ancestor born before 1850 in a particular parish, generated live from your notes? Dataview can build it.
- Templater — creates reusable templates, so every new “person” note or “source” note starts with the same structure: birth, death, parents, spouse, sources, open questions. This brings a welcome bit of consistency to research notes that would otherwise vary wildly in quality and completeness.
- Excalidraw — for sketching farm layouts, hand-drawn family trees, or migration routes directly inside a note.
- Kanban — useful for tracking research tasks in progress: “waiting on archive response,” “need to verify,” “confirmed.”
- Citations / Zotero integration — for those who manage sources through a reference manager and want that linked into their notes.
None of these are required to get value from Obsidian. But the fact that they exist, are free, and are maintained by an active community means the tool keeps growing to meet needs you haven’t even identified yet.
The Free Part Is Not a Trick
Obsidian’s core application is free for personal use, full stop — no feature-gating, no trial period, no nagging to upgrade. Optional paid add-ons exist (Obsidian Sync, for syncing across devices, and Obsidian Publish, for turning a vault into a public website), but they’re genuinely optional.
For a genealogist building a personal knowledge base that might grow for decades, that low barrier to entry — and low risk of the tool disappearing or changing pricing under you — matters more than it might for a casual user.
Using Obsidian Across Devices — and How Syncing Actually Works
A “vault,” in Obsidian’s language, is simply the folder on your computer where all your notes live. Because everything is stored as plain text files rather than in a proprietary database, getting that folder onto more than one device is really just a matter of keeping the folder itself in sync — Obsidian doesn’t need to be involved in the syncing at all. That said, there are a few different ways to do it, each with its own trade-offs.
Obsidian Sync (paid, official). This is Obsidian’s own subscription service (roughly $4–8/month depending on plan). It syncs your vault end-to-end encrypted across desktop and mobile, keeps a version history of every note, and can selectively sync just some folders if your vault gets very large. It’s the simplest option if you want something built specifically for Obsidian and don’t mind paying a small monthly fee. It also works well with vaults containing lots of attached images and PDFs of scanned records, which can otherwise strain free syncing methods.
Cloud storage folders (free). The most common free approach is simply putting your vault folder inside Dropbox, iCloud Drive, OneDrive, or Google Drive, and letting that service handle the syncing the way it would for any other folder. This works well for most people, with two caveats worth knowing before you rely on it:
- Sync conflicts. If you edit the same note on two devices while offline, most of these services will create a duplicate “conflicted copy” file rather than merging your changes. This is rare if you get in the habit of closing Obsidian on one device before opening it on another, but worth knowing about.
- The hidden
.obsidianfolder. Your plugin settings, themes, and hotkeys live in a hidden subfolder called.obsidian. Cloud services sometimes handle hidden folders inconsistently, so it’s worth checking that yours is actually syncing this folder if you want your plugin setup to follow you between devices.
Syncthing (free, more technical). For those comfortable with a bit more setup, Syncthing is a free, open-source tool that syncs folders directly between your own devices — no cloud provider in the middle at all. It’s popular in the Obsidian community precisely because it avoids the “conflicted copy” problem better than most cloud drives, and keeps everything entirely under your own control. It takes a little longer to configure than simply dropping a folder into Dropbox, but many genealogists who are already comfortable managing digitized records and backups find it a natural fit.
Git-based syncing (free, most technical). There’s also a community plugin, Obsidian Git, that syncs your vault through Git version control — the same system programmers use to track code changes. This gives you a complete, searchable history of every change ever made to every note, which has an obvious appeal for research work where you sometimes need to see what you believed six months ago before you found the record that corrected it. It’s overkill for most users, but worth knowing it exists if your vault becomes central to your research process.
Mobile access. Whichever syncing method you choose, the free Obsidian apps for iOS and Android let you open your vault on a phone or tablet — genuinely useful if you ever find yourself typing notes into your phone at an archive or library, or snapping a photo of a document and dropping it straight into a note on the spot. The mobile interface takes a little getting used to, particularly for anything involving plugins with complex layouts, but core note-taking and linking work smoothly.
For most genealogists starting out, I’d suggest simply using whatever cloud storage you already have (iCloud or Dropbox, say) and only stepping up to Syncthing or paid Obsidian Sync once your vault has grown large enough, or become important enough, that the small conveniences start to matter.
Getting Started Without Overwhelming Yourself
The temptation with a tool this flexible is to try to build the perfect system on day one. Don’t. My advice, from my own stumbling start:
- Start with one family line. Don’t try to migrate your entire tree at once.
- Make one simple template for a person note and one for a source note. Refine them as you go — you will refine them, repeatedly.
- Link generously. Every name you type, link it, even to a note that doesn’t exist yet. Obsidian will create it, and you can fill it in later.
- Check the graph view every so often, not to admire it, but to notice where it’s telling you something — a cluster you haven’t explored, an isolated name that needs more digging.
- Resist plugin overload at first. Learn the core linking habit before adding Dataview queries and Kanban boards on top.
A Tool Worth the Learning Curve
Obsidian won’t replace a proper genealogy database — it doesn’t handle GEDCOM files, generate pedigree charts, or manage source citations in a standardized format the way dedicated genealogy software does. What it does instead is give you a place to think about your research: to hold the uncertainty, the half-formed hypotheses, the “this doesn’t add up yet” notes that don’t fit neatly into a family tree program’s rigid fields.
Used alongside your genealogy software rather than instead of it, Obsidian becomes something like a research journal that organizes itself as you write — a web of ancestors, sources, and open questions that grows exactly as tangled and as clear as your actual research does.
I’m still exploring what this tool can do, and I suspect I’ve only scratched the surface of what the plugin ecosystem makes possible. If you’re already using Obsidian for your own family history work, I’d love to hear how you’ve set up your vault — there’s a good chance you’ve solved a problem I haven’t even run into yet.
