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