Data-Driven Genealogy: Charting My Ancestors

Data holds incredible power - it highlights gaps in knowledge, bridges them, and gives our research purpose and direction. When it comes to genealogy, data can reveal fresh perspectives on our ancestors' stories, offering new insights into where we come from.

For years, I’ve been mapping my family tree in every way imaginable. A particularly important approach is charting my ancestors by their birthplaces. The result? A vibrant, visual journey that showcases how "the story of me" began almost everywhere. The map is a kaleidoscope of colors - each representing a different ancestral birthplace - capturing a history so diverse it's almost overwhelming.

Mapping Life’s Journey: The Key to Unlocking Documents and Stories


Mapping your ancestors’ birth, life, and death locations is essential if you’re serious about uncovering the documents that tell their life stories. After all, you can’t know where to search for their records if you don’t know where they lived.

I’ve taken this a step further by mapping my ancestors’ burial locations across the United States. In late 2020, I embarked on a socially-distanced cross-country road trip. Along the way, I shaped my route to include stops at cemeteries where my ancestors are buried. This journey, which I recorded in, Ancestors Across the Heartland: A Family History Road Trip, became an opportunity not just to connect with living relatives but also to “commune” with my past.

Keeping Score: Who Am I Missing?


Early in my genealogy journey, I developed a habit of stepping back each year to crunch the numbers. I’d pause my research long enough to take a big-picture view and tally the direct ancestors I’d added to my tree over the past 12 months. This annual exercise became an opportunity to measure my progress from a purely quantitative perspective.

While I don’t approach genealogy as a numbers game, monitoring numeric benchmarks provides a simple and tangible way to gauge growth in my research. These periodic check-ins remind me not just of how far I’ve come, but also of who is still missing from the story (see My 2020 Ancestor Tally).

Comparing Myself to My Ancestors


Genealogy data has become more than just a tool for tracing family history - I've also used it as a fascinating point of comparison with my own life. 

Concerned about not being a parent yet? I've turned to my family tree for reassurance, asking: How old were my ancestors when they had the child who would eventually lead to me? Turns out, there's a chart for that! And I've got plenty of time - my 3rd great-grandfather, John Flynn fathered my ancestor John at the age of 49! (See Ancestors' Ages at Parenthood)

Wondering about my life expectancy? I've examined my ancestors' ages at death to see what the numbers might suggest about my own longevity. It's a bit macabre, sure, but also insightful. Here's hoping I inherited my second great-grandmother Minnie's genes - she lived to 92, making her my longest-lived ancestor! (See Longevity Pedigree: Crunching the Numbers)


And then there's my genetic pedigree. By mapping my ancestors' haplogroups, I've gained a deeper understanding of DNA inheritance across my pedigree. (See The Genetic Family Tree Grows New Buds)

Uncovering the Past Through Data


Genealogy is more than names and dates - it's about uncovering stories, patterns, and connections that define who we are. By mapping and charting data like birthplaces, life events, and even genetics, we gain insights into our ancestors' journeys and how they shape our own. Whether it's comparing life milestones, exploring longevity, or creating visual charts of family connections, data brings clarity and meaning to the past.

  1. I loved this post so much. I, too, am a numbers person and prefer color visualization. You have inspired me today to get back into it. I also want to make a cemetery map like you did on the ones you visited and the ones you still need to. Rock on!

    1. Thanks, Paul. I appreciate it. I find the visualization helps me see my research with new eyes and spot gaps or better focus my efforts. Google maps has been a great resource for mapping my data. Good luck mapping your ancestors' burials. Sounds like the beginnings of an epic road trip.
