The maternal relationship between Ruth Prain and her son Kenneth Schafer is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant RS.

The segmental (via DNA segment triangulation) and total DNA shared between RS and other confirmed descendants of Martin Ramthun is consistent with the expected ranges for their respective relationships. Since RS descends from Martin Ramthun through Ruth Prain and her son Kenneth Schafer, the presence of significant shared DNA between RS and other known descendants of Martin Ramthun validates the generational links along this maternal line.

This supports the conclusion that DNA was passed from MRCA Martin Ramthun through Ruth Prain to Kenneth Schafer, and ultimately to RS, confirming this direct ancestral connection through multiple generations.
