The maternal relationship between Blanche Viola Streitz and her daughter
Susan Elizabeth Dionne is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant AR.
The segmental (via DNA segment triangulation) and total DNA shared between AR and other confirmed descendants of
John Denean/
Elizabeth Jean Alleman is consistent with the expected ranges for their respective relationships. Since AR descends from John Denean/Elizabeth Jean Alleman through Blanche Viola Streitz and her daughter Susan Elizabeth Dionne, the presence of significant shared DNA between AR and other known descendants of John Denean/Elizabeth Jean Alleman validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple John Denean/Elizabeth Jean Alleman through Blanche Viola Streitz to Susan Elizabeth Dionne, and ultimately to AR, confirming this direct ancestral connection through multiple generations.
