The maternal relationship between Margaret Lenore Brown and her DNA tested daughter TF is confirmed by the direct inheritance path of autosomal DNA.
The segmental (via DNA segment triangulation) and total DNA shared between TF and other confirmed descendants of
John Francis Delong/
Sarah Winteringer is consistent with the expected ranges for their respective relationships. Since TF descends from John Francis Delong/Sarah Winteringer through Margaret Lenore Brown, the presence of significant shared DNA between TF and other known descendants of John Francis Delong/Sarah Winteringer validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple John Francis Delong/Sarah Winteringer through Margaret Lenore Brown to TF, confirming this direct ancestral connection through multiple generations.
