The paternal relationship between Johann Ramthun and his daughter
Bertha Ramthun is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant CB.
The segmental (via DNA segment triangulation) and total DNA shared between CB and other confirmed descendants of
Martin Ramthun/
Luise Glander is consistent with the expected ranges for their respective relationships. Since CB descends from Martin Ramthun/Luise Glander through Johann Ramthun and his daughter Bertha Ramthun, the presence of significant shared DNA between CB and other known descendants of Martin Ramthun/Luise Glander validates the generational links along this paternal line.
This supports the conclusion that DNA was passed from MRCA couple Martin Ramthun/Luise Glander through Johann Ramthun to Bertha Ramthun, and ultimately to CB, confirming this direct ancestral connection through multiple generations.
