The FAN Club: Solving Problems Through Friends, Associates and Neighbors
When your ancestor's own records run out, the people around them can still lead the way. A step-by-step guide to cluster research.
Sooner or later, every researcher hits an ancestor who seems to appear from nowhere: no birthplace, no parents, no earlier records. The answer is often to stop looking only at the ancestor and study the people around them. Genealogist Elizabeth Shown Mills named this the FAN principle, for Friends, Associates and Neighbors. Researchers also call it cluster research.
Why it works
People rarely moved alone. Families migrated in groups: siblings, in-laws, neighbors from the same church or county. They witnessed each other's deeds, signed each other's marriage bonds, married each other's children, and settled next to each other on the frontier. If your ancestor has no trail, someone in his circle often does. Find where they came from, and you've likely found where he came from too.
Step 1: Build the cluster
Go through every record you have for your ancestor and list every other name that appears:
- Neighbors listed on either side of the family in each census
- Witnesses to deeds, wills and marriages
- Bondsmen on marriage bonds, estate bonds and guardianships
- Adjoining landowners named in deeds and surveys
- Sponsors and godparents at baptisms
- Buyers at estate sales, and people in the same church, lodge or military company
Put them in a spreadsheet, with columns for each record and year. Names that appear again and again are your core cluster.
Step 2: Look for patterns
Sort the list and look for:
- Repeat appearances: a man who witnessed three of your ancestor's documents is probably family or a close friend.
- Shared surnames: an unusual surname that keeps appearing may be the ancestor's mother's or wife's family.
- Moves together: if five families from your ancestor's neighborhood all appear together in another county ten years earlier, you've likely found the previous home.
Step 3: Research the cluster backward
Pick the best-documented people in the cluster and trace them back. If several came from the same county, search that county's tax lists, deeds and church records for your ancestor's surname. You now have a specific place to look instead of a whole state.
A worked example
Suppose John Miller appears in an 1830 Indiana county with no clue to his origin. His 1832 deed is witnessed by Robert Gwinn and Samuel Ash, and his neighbors in the 1830 census include two Gwinn households and an Ash. Tracing the Gwinns shows they came from a particular county in Virginia around 1828. In that county's tax lists, a John Miller appears from 1815 to 1827, then vanishes, the same year the Gwinns left. That's not proof yet, but it's a strong lead. Test it with more records, using the Genealogical Proof Standard.
Tips
- Record every name, even ones that seem unimportant. You won't know which matter until later.
- Map the land. Platting deeds shows who lived next to whom, which a census list only approximates.
- Be patient. Cluster research takes time, but it's how many long-standing brick walls finally come down.
