I’ve combined Amy Johnson Crow’s 52 ancestors in 52 weeks challenge, and Steve Little’s The 2025 AI Genealogy Do-Over, to create a unique 52 AI ancestors in 52 weeks party!
52 AI Ancestors in 52 Weeks: Week 3: Nickname
Introduction
Week 3 of the 52 Ancestors challenge dives into nicknames. “Which of your ancestors had a nickname? Do you know how they got it?”
This week, I’ll step away from my maternal grandmother’s line to focus on my paternal grandmother’s mother, my great-grandmother Mary Agnes HART CAREY (1892-1978) —known to us as “Nanny.”
Background
Great Grandma, “Nanny” we called her, was named Mary Agnes HART CAREY. She was born, you might have guessed, into an Irish Catholic family.
The nickname
Her formal name, Mary Agnes, seemed typical for her heritage and era, but it also carried a hidden twist: she was universally called “Aggie.”
My grandmother shared how, after Nanny passed, she was shocked to learn her mother’s first name wasn’t actually “Agnes.” Nanny named one of her children “Agnes,” but not “Mary,” indicating how she wanted to leave the name behind.
Nicknames like “Aggie” often reflect personal preferences, family traditions, or even community influences. But what’s fascinating is how these seemingly small details offer insights into how ancestors presented themselves to the world or were seen by others.

The AI Connection: How AI Can Help Decode Nicknames
Nicknames can be tricky in genealogy, especially when records use formal names instead of the name your ancestor was commonly called. AI tools can be a game-changer here by offering innovative ways to trace and decode these hidden connections:
- Name Matching in Records
AI-powered genealogy platforms can identify patterns in historical records, connecting nicknames to formal names. For example, searching for “Aggie” might yield records for Mary Agnes, even if “Aggie” isn’t explicitly listed. AI algorithms that analyze phonetic similarities (like the Soundex system) make this possible. - Document Analysis
Some AI tools can scan personal letters, diaries, or even old newspapers to detect nicknames alongside formal names. This can help clarify how nicknames were used and even uncover clues about their origins. - Family Tree Suggestions
Platforms like Ancestry.com and MyHeritage use AI to suggest connections. If an ancestor was known by different names in various documents, AI can consolidate the data, revealing hidden patterns or relationships you might otherwise miss. - Cultural Context Insights
AI can also analyze naming trends by era and region. For instance, “Aggie” as a nickname for Agnes was more popular in Irish communities during certain periods. Understanding these trends can make your ancestor’s story richer and more relatable.
Going Forward
What about you? Who in your family had a nickname that stood out? Did it reveal a personality quirk, a fond memory, or a cultural connection?
Take this week’s challenge to the next level by pairing your research with AI tools. You might discover a nickname hiding in plain sight or uncover how a loved one’s identity evolved over time.
