DNA Clustering and the Leeds Method: Making Sense of Your Match List

No Comments
| Genetic Genealogy
Diagonal color-coded collaboration heatmap with name labels along the top and left; red, orange, yellow, green, and blue blocks show clustered activity across the matrix.

What’s in a Name: Naming Patterns in the Dillman Family Groups

No Comments
| Dillman Families
Word cloud of many German names on a dark blue background; largest names include Johann, Dillmann, Diehlmann, Conrad, Johannes, Heinrich.

The 160 family groups in the DFA database reveal consistent naming patterns across two centuries of Dillman migration — from the dominance of Johann in German records to the predictable anglicization that turned Heinrich into Henry and Georg into George at the American border.

No Comments
| Genetic Genealogy
Karyotype image showing human chromosomes arranged in pairs, totaling 46 chromosomes in a standard layout.
