The paternal relationship between John Douglas Kubitschek and his daughter
Coleen Rose Kubitschek is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant VN.
The segmental (via DNA segment triangulation) and total DNA shared between VN and other confirmed descendants of
Nicholas Forret/
Margaret L Fehlen is consistent with the expected ranges for their respective relationships. Since VN descends from Nicholas Forret/Margaret L Fehlen through John Douglas Kubitschek and his daughter Coleen Rose Kubitschek, the presence of significant shared DNA between VN and other known descendants of Nicholas Forret/Margaret L Fehlen validates the generational links along this paternal line.
This supports the conclusion that DNA was passed from MRCA couple Nicholas Forret/Margaret L Fehlen through John Douglas Kubitschek to Coleen Rose Kubitschek, and ultimately to VN, confirming this direct ancestral connection through multiple generations.
