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