The maternal relationship between Sarah Emily Pennington and her daughter
Emily Jane Terrell is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant RASDB.
The segmental (via DNA segment triangulation) and total DNA shared between RASDB and other confirmed descendants of
Timothy Pennington/
Nancy Susannah Riggs is consistent with the expected ranges for their respective relationships. Since RASDB descends from Timothy Pennington/Nancy Susannah Riggs through Sarah Emily Pennington and her daughter Emily Jane Terrell, the presence of significant shared DNA between RASDB and other known descendants of Timothy Pennington/Nancy Susannah Riggs validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple Timothy Pennington/Nancy Susannah Riggs through Sarah Emily Pennington to Emily Jane Terrell, and ultimately to RASDB, confirming this direct ancestral connection through multiple generations.
