The paternal relationship between Mikael Strandlund and his daughter
Lena Strandlund is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant AS.
The segmental (via DNA segment triangulation) and total DNA shared between AS and other confirmed descendants of
Jonas Bertilsson Ofwerman/
Brita Olofsdotter is consistent with the expected ranges for their respective relationships. Since AS descends from Jonas Bertilsson Ofwerman/Brita Olofsdotter through Mikael Strandlund and his daughter Lena Strandlund, the presence of significant shared DNA between AS and other known descendants of Jonas Bertilsson Ofwerman/Brita Olofsdotter validates the generational links along this paternal line.
This supports the conclusion that DNA was passed from MRCA couple Jonas Bertilsson Ofwerman/Brita Olofsdotter through Mikael Strandlund to Lena Strandlund, and ultimately to AS, confirming this direct ancestral connection through multiple generations.
