The paternal relationship between Per Persson Berglund and his son Jonas Gustaf Berglund is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant FG.

The segmental (via DNA segment triangulation) and total DNA shared between FG and other confirmed descendants of Samuel Larsson is consistent with the expected ranges for their respective relationships. Since FG descends from Samuel Larsson through Per Persson Berglund and his son Jonas Gustaf Berglund, the presence of significant shared DNA between FG and other known descendants of Samuel Larsson validates the generational links along this paternal line.

This supports the conclusion that DNA was passed from MRCA Samuel Larsson through Per Persson Berglund to Jonas Gustaf Berglund, and ultimately to FG, confirming this direct ancestral connection through multiple generations.
