The paternal relationship between Pehr Jonsson and his son Per Persson 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 Pehr Jonsson and his son Per Persson 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 Pehr Jonsson to Per Persson Berglund, and ultimately to FG, confirming this direct ancestral connection through multiple generations.
