DNA & Genetic Genealogy for SC Families
How DNA helps—and how endogamy and migration corridors complicate matches.
Autosomal DNA can reconnect lost branches, especially where records burned. SC Upstate and some Lowcountry communities show clustering and endogamy: shared matches may reflect multiple historical connections, not one couple. Always anchor DNA with documentary research.
- Build a solid tree before interpreting cluster matches.
- Use targeted testing of older generations when ethical and possible.
- Y-DNA/mtDNA can test specific surname or maternal hypotheses.
