Occupational Tracking: When Name Searches Fail
You've searched every census. You've scoured city directories. You've analyzed DNA matches until your eyes crossed. But when your ancestor has one of the most common surnames in a city of 800,000 people—John Smith, Mary Jones, James Kelly—traditional name-based genealogy hits a wall. What if I told you there's another way?
For seven years, I searched for a man named John Kenny among dozens of Brooklyn mat makers with virtually identical names. Census records, marriage certificates, city directories—they all showed multiple John Kennys in the exact same neighborhood, working the exact same trade, living at the exact same time.
Traditional genealogy methods couldn't distinguish between them. But occupational tracking methodology could—and did.
This post will teach you how to use career progression as a unique identifier when name searches fail. It's a technique I developed through years of frustration, breakthrough, and ultimately success. And it's helped solve research problems that had stymied family historians for generations.
The Common Surname Problem
Here's the scenario that stops genealogists in their tracks:
- Common surname: Kenny, Kelly, Smith, Murphy, O'Brien
- Common given name: John, Mary, James, Margaret
- Common location: Densely populated immigrant neighborhoods
- Common occupation: Laborer, domestic servant, factory worker
- Limited documentation: Pre-1900 records with minimal detail
When you combine these factors, traditional name-based searching becomes nearly impossible. You might find 15 John Kennys in Brooklyn in 1880. They're all Irish immigrants. They're all approximately the same age. Some even live in the same ward.
How do you know which one is yours?
Why Traditional Methods Reach Their Limit
Name Searches Assume Uniqueness
Most genealogy databases are built around name searches. FamilySearch, Ancestry, MyHeritage—they all start with "enter a name." This works beautifully when your ancestor is Zachariah Pumpernickel from rural Vermont. It fails spectacularly when your ancestor is John Kelly from urban Boston.
The algorithms can't distinguish between:
- John Kelly, age 35, laborer, living on Cherry Street
- John Kelly, age 37, laborer, living on Cherry Street (different person!)
- John Kelly, age 35, carpenter, living on Mulberry Street (your ancestor)
Census Records Provide Snapshots, Not Stories
A census record tells you where someone was on one day every ten years. It doesn't tell you:
- How they got there
- Where they came from
- What they did between censuses
- How their career evolved
These gaps become critical when you're trying to distinguish between similarly named individuals.
City Directories List Everyone with the Same Occupation
Brooklyn city directories in the 1870s-1880s list dozens of "mat makers" named Kenny. Without additional identifying information, you can't tell them apart. The directory might show:
Kenny John, mat maker, h. 145 Graham av
Kenny John, mat maker, h. 213 South 2d
Kenny John, mat maker, h. 89 North 3d
Kenny John J., mat maker, h. 67 Bedford av
All four could be your ancestor. Or none of them. Traditional methods can't tell you which.
The Solution: Occupational Tracking
Core Principle: When names are common, occupational progression becomes a unique identifier. Track the career, not just the name.
Here's the insight that changed everything: While many people might share a name and occupation at one point in time, very few will follow the exact same career progression over decades.
Think about it:
- Dozens of John Kennys might work as mat makers in 1870
- But how many start as mat makers, then advance to hatters, then own their own hat shop?
- How many make that specific progression in the same neighborhood over the same time period?
- How many also have wives with specific maiden names that tie to other research findings?
Suddenly, you're not looking for one of fifty John Kennys. You're looking for one specific career trajectory that belongs to only one person.
How Occupational Tracking Works: The Method
Step 1: Map Every Known Occupation Reference
Go through every document you have and extract occupation information. Don't limit yourself to census records—check city directories, marriage records, birth certificates, death certificates, newspaper articles, even advertisements. Create a timeline showing occupation at each date.
Step 2: Identify Occupational Progression Patterns
Look for career advancement or specialization. Did they start as an apprentice and advance to journeyman? Did they move from "laborer" to a specific skilled trade? Did they progress from employee to shop owner? These progressions are like fingerprints.
Step 3: Track Related Trades and Industries
Understand the industry ecosystem. Mat makers often worked in hat factories. Hatters might also list as "furriers" or "felt workers." Carpenters might be listed as "builders" or "contractors." Knowing related trades helps you find the same person under slightly different occupation labels.
Step 4: Use Geographic Clustering
Certain trades clustered in specific neighborhoods. Brooklyn's hat-making district was concentrated in particular wards. Combine occupational data with geographic data to narrow the field. Your John Kenny the mat maker living in Ward 21 is more likely to be in the hat-making district than Ward 5.
Step 5: Cross-Reference with Family Members
Look at occupations of sons, brothers, fathers. Trades often ran in families. If you know your John Kenny's father was a hatter, and you find a John Kenny working as a hatter in the right location and time period, you've likely found your person—even if the name alone wouldn't be enough.
Step 6: Build Sequential Evidence Chains
Document each step of the career progression with primary sources. Show that the same individual appears consistently with logical career advancement. This creates a chain of evidence that's much stronger than any single document.
Real-World Example: The Brooklyn Mat Maker
Let me show you how this worked in practice with my seven-year search for John Kenny.
The Challenge
I knew from family documents that my great-great-grandfather John Kenny:
- Born circa 1840 in Ireland
- Married Margaret McKenny (also very common names)
- Lived in Brooklyn in the 1870s-1880s
- Worked in the hat-making industry
When I searched "John Kenny" in Brooklyn during this period, I found over fifty men with that exact name. Many were Irish immigrants. Many were approximately the right age. Several worked in related trades.
Traditional genealogy methods couldn't distinguish between them.
The Occupational Tracking Breakthrough
Instead of searching for "John Kenny," I started tracking occupational progression in the hat-making industry:
1870: Mat maker (entry-level position in hat industry)
1875-1879: Consistently listed as "mat maker" in directories
1880: Still mat maker, but now in heart of hat-making district
1882: Baptism record shows occupation "hatter" (advancement!)
1885: City directory lists "hatter" at new address
1888: Death certificate confirms "hatter" occupation
This specific progression—from mat maker to hatter in Brooklyn's Ward 21 over an 18-year period—matched only one John Kenny.
The Four Words That Changed Everything
The breakthrough came in an 1879 Brooklyn city directory. While most entries simply listed "Kenny John, mat maker," one entry was different:
Elizabeth Kenny was listed as a widow. The directory placed her at the same address where one of the John Kennys lived. This wasn't a John Kenny entry—but it identified his mother, Elizabeth, widow of Richard Kenny.
Now I wasn't just tracking an occupation. I was tracking an occupation plus a family connection. This combination was unique enough to definitively identify the correct John Kenny.
Occupational tracking didn't just find my ancestor—it revealed his entire family structure, career trajectory, and social network.
When to Use Occupational Tracking
This methodology works best when you face specific research challenges:
✓ Perfect Candidates for Occupational Tracking
- Common surnames in urban areas: Kelly, Murphy, Smith, Cohen, Garcia
- Skilled trades with progression: Apprentice → journeyman → master
- Industry-specific occupations: Hat makers, printers, shipbuilders
- Well-documented time periods: 1850-1930 with good city directories
- Immigrant communities: Where many share names and occupations
⚠ When This Method Has Limitations
Occupational tracking is less effective when: (1) Your ancestor frequently changed occupations without pattern, (2) Records list only "laborer" or very generic terms, (3) You're researching before 1850 or after 1940 when documentation differs, or (4) Your ancestor lived in rural areas with few occupation-specific records. In these cases, you'll need to rely more heavily on other identification methods like DNA, property records, or witness patterns.
Getting Started: Your Action Plan
Ready to try occupational tracking for your own research? Here's how to begin:
Create Your Occupation Timeline
Open a spreadsheet and create columns for: date, source type (census, directory, certificate), exact occupation listed, location, and other identifying details. Fill in every occupation reference you can find, even if you're not sure they're all the same person yet.
Research the Industry
Learn about the specific trade. What were the career progression steps? What related occupations existed? Where did this industry cluster geographically? Were certain immigrant groups dominant in this trade? Local historical societies, industry histories, and occupational dictionaries can help immensely.
Look for Patterns
Examine your occupation timeline for logical progressions (apprentice → journeyman → master), related occupations that fit the same industry, geographic consistency with industry clusters, and unique combinations that distinguish one person from others.
Expand Your Source Base
Don't limit yourself to census and directories. Check baptism/marriage records (often list occupation), death certificates (list last known occupation), naturalization papers (list occupation at time of filing), newspaper articles (especially trade journals or strike coverage), business directories (separate from residential directories), and union records (if applicable to the trade).
Document Your Evidence Chain
As you identify the career progression, document it thoroughly. Cite every source (follow BCG standards), explain why each occupation reference likely refers to the same person, address potential conflicting information, and show how the occupational progression supports your conclusion.
Key Takeaways
1. Names alone often can't identify ancestors in crowded immigrant neighborhoods. You need additional distinguishing factors.
2. Occupational progression is a powerful unique identifier. While many people might share a name and occupation at one point, few follow the exact same career trajectory.
3. Understanding industry context is crucial. Know the related trades, typical career progressions, and geographic clustering patterns.
4. City directories are your secret weapon. They provide annual occupation snapshots that census records can't offer.
5. Build evidence chains, not single-document conclusions. Sequential occupational progression across multiple sources creates strong proof.
