The maternal relationship between Bertha Emilie Alwina Parlow and her son Albert Carl August Rakow is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant PELR.

The segmental (via DNA segment triangulation) and total DNA shared between PELR and other confirmed descendants of Carl Heinrich Pahlow/Wilhelmine Ramthun is consistent with the expected ranges for their respective relationships. Since PELR descends from Carl Heinrich Pahlow/Wilhelmine Ramthun through Bertha Emilie Alwina Parlow and her son Albert Carl August Rakow, the presence of significant shared DNA between PELR and other known descendants of Carl Heinrich Pahlow/Wilhelmine Ramthun validates the generational links along this maternal line.

This supports the conclusion that DNA was passed from MRCA couple Carl Heinrich Pahlow/Wilhelmine Ramthun through Bertha Emilie Alwina Parlow to Albert Carl August Rakow, and ultimately to PELR, confirming this direct ancestral connection through multiple generations.
