The paternal relationship between Leonard Peter Kremers and his son FK is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant JK.

The segmental (via DNA segment triangulation) and total DNA shared between JK and other confirmed descendants of Josephus D'Hondt/Cordula Maria De La Sorte is consistent with the expected ranges for their respective relationships. Since JK descends from Josephus D'Hondt/Cordula Maria De La Sorte through Leonard Peter Kremers and his son FK, the presence of significant shared DNA between JK and other known descendants of Josephus D'Hondt/Cordula Maria De La Sorte validates the generational links along this paternal line.

This supports the conclusion that DNA was passed from MRCA couple Josephus D'Hondt/Cordula Maria De La Sorte through Leonard Peter Kremers to FK, and ultimately to JK, confirming this direct ancestral connection through multiple generations.
