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