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