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