The paternal relationship between John Addison Leavitt and his son
John Calvin Leavitt is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant GF.
The segmental (via DNA segment triangulation) and total DNA shared between GF and other confirmed descendants of
John Wheeler Leavitt/
Silence Fitch is consistent with the expected ranges for their respective relationships. Since GF descends from John Wheeler Leavitt/Silence Fitch through John Addison Leavitt and his son John Calvin Leavitt, the presence of significant shared DNA between GF and other known descendants of John Wheeler Leavitt/Silence Fitch validates the generational links along this paternal line.
This supports the conclusion that DNA was passed from MRCA couple John Wheeler Leavitt/Silence Fitch through John Addison Leavitt to John Calvin Leavitt, and ultimately to GF, confirming this direct ancestral connection through multiple generations.
