The maternal relationship between Sophia Olofsdotter Sundell and her son
Johan Larsson Nyman is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant AI.
The segmental (via DNA segment triangulation) and total DNA shared between AI and other confirmed descendants of
Olof Sundell/
Dordi Nilsdotter is consistent with the expected ranges for their respective relationships. Since AI descends from Olof Sundell/Dordi Nilsdotter through Sophia Olofsdotter Sundell and her son Johan Larsson Nyman, the presence of significant shared DNA between AI and other known descendants of Olof Sundell/Dordi Nilsdotter validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple Olof Sundell/Dordi Nilsdotter through Sophia Olofsdotter Sundell to Johan Larsson Nyman, and ultimately to AI, confirming this direct ancestral connection through multiple generations.
