The paternal relationship between Leon Andre and his daughter EA is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant JA.
The segmental (via DNA segment triangulation) and total DNA shared between JA and other confirmed descendants of
Louis Julien Andre/
Julia Eugenie Therese Bary is consistent with the expected ranges for their respective relationships. Since JA descends from Louis Julien Andre/Julia Eugenie Therese Bary through Leon Andre and his daughter EA, the presence of significant shared DNA between JA and other known descendants of Louis Julien Andre/Julia Eugenie Therese Bary validates the generational links along this paternal line.
This supports the conclusion that DNA was passed from MRCA couple Louis Julien Andre/Julia Eugenie Therese Bary through Leon Andre to EA, and ultimately to JA, confirming this direct ancestral connection through multiple generations.
