The paternal relationship between Grant Emmett Van Wagenen and his son
Roy Emmett Van Wagenen is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant KVW.
The segmental (via DNA segment triangulation) and total DNA shared between KVW and other confirmed descendants of
David Van Wagenen/
Julia Ann Provost is consistent with the expected ranges for their respective relationships. Since KVW descends from David Van Wagenen/Julia Ann Provost through Grant Emmett Van Wagenen and his son Roy Emmett Van Wagenen, the presence of significant shared DNA between KVW and other known descendants of David Van Wagenen/Julia Ann Provost validates the generational links along this paternal line.
This supports the conclusion that DNA was passed from MRCA couple David Van Wagenen/Julia Ann Provost through Grant Emmett Van Wagenen to Roy Emmett Van Wagenen, and ultimately to KVW, confirming this direct ancestral connection through multiple generations.
