DNA STRUCTURE OF THE APPALACHIAN OSBORNE LINE
R-L1066 - Y-DNA FRAMEWORK- ACTIVE DATASET
This page defines the genetic structure used to evaluate the Appalachian Osborne lineage.
All conclusions on this site are grounded in Y-DNA analysis and supported—where appropriate—by historical records.
CORE HAPLOGROUP
The Appalachian Osborne paternal line is defined by:
R-L1066
This haplogroup represents a distinct paternal population associated with the Irish Sea region.
It provides the biological baseline for identifying related Osborne lines.
REFINEMENT
Current data suggests a possible downstream refinement:
R-BY82341 (provisional)
This classification is under evaluation and is awaiting additional Big-Y testing for confirmation.
No final subclade assignment is assumed at this stage.
PROJECT POSITION / LIMITATIONS OF EXISTING SURNAME PROJECTS
The current Osborne surname project structure is limited by:
• Inactive or unavailable administration
• Legacy lineage assignments based on incomplete data
• Lack of integration with modern DNA refinement methods
As a result, lineage interpretation must be conducted independently using current datasets and controlled analysis.
DNA TABLE / WORKING DATASET
The table below represents the current working structure of the R-L1066 Osborne cluster.
Testers are identified by kit number only.
This dataset is updated as new results become available.
HOW TO READ THE CHART
Each row represents a Y-DNA test from a male in the Osborne line.
The values compare genetic markers passed from father to son.
A smaller difference between two results indicates a closer relationship.
A larger difference indicates a more distant connection or a separate line.
This allows us to group individuals into biological clusters rather than relying on surname alone.
INTERPRETATION RULES / STANDARDS
This project follows three rules:
• Y-DNA defines the paternal line
• Genetic distance determines relationship proximity
• Autosomal DNA is used only as supporting evidence—not primary lineage proof
All interpretations are provisional and subject to revision as new data becomes available.
TESTING
To participate in this project, testing must be completed through FamilyTreeDNA.
Recommended tests:
• Y-111 (baseline comparison)
• Big-Y 700 (deep lineage refinement)
Additional results strengthen the accuracy of this dataset and improve lineage resolution.
PROJECT STATUS
This dataset represents an active research structure.
It is not a finalized lineage.
As new test results are introduced, classifications and relationships will be refined accordingly.
Accuracy is prioritized over tradition.
