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