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