The paternal relationship between Isaac Smith Peet and his daughter PEP is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant DL.

The segmental (via DNA segment triangulation) and total DNA shared between DL and other confirmed descendants of George William Peet/Jeanie Taylor Smith is consistent with the expected ranges for their respective relationships. Since DL descends from George William Peet/Jeanie Taylor Smith through Isaac Smith Peet and his daughter PEP, the presence of significant shared DNA between DL and other known descendants of George William Peet/Jeanie Taylor Smith validates the generational links along this paternal line.

This supports the conclusion that DNA was passed from MRCA couple George William Peet/Jeanie Taylor Smith through Isaac Smith Peet to PEP, and ultimately to DL, confirming this direct ancestral connection through multiple generations.
