The maternal relationship between Brita Larsdotter and her daughter
Maria Isacsdotter is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant NS.
The segmental (via DNA segment triangulation) and total DNA shared between NS and other confirmed descendants of
Samuel Larsson is consistent with the expected ranges for their respective relationships. Since NS descends from Samuel Larsson through Brita Larsdotter and her daughter Maria Isacsdotter, the presence of significant shared DNA between NS and other known descendants of Samuel Larsson validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA Samuel Larsson through Brita Larsdotter to Maria Isacsdotter, and ultimately to NS, confirming this direct ancestral connection through multiple generations.
