The paternal relationship between Lawrence J Keller and his DNA tested daughter RL is confirmed by the direct inheritance path of autosomal DNA.
The segmental (via DNA segment triangulation) and total DNA shared between RL and other confirmed descendants of
Johann Baptist Fessler/
Elisabetha Maria Schmitz is consistent with the expected ranges for their respective relationships. Since RL descends from Johann Baptist Fessler/Elisabetha Maria Schmitz through Lawrence J Keller, the presence of significant shared DNA between RL and other known descendants of Johann Baptist Fessler/Elisabetha Maria Schmitz validates the generational links along this paternal line.
This supports the conclusion that DNA was passed from MRCA couple Johann Baptist Fessler/Elisabetha Maria Schmitz through Lawrence J Keller to RL, confirming this direct ancestral connection through multiple generations.
