The maternal relationship between Robin Lynne Willems and her DNA tested son JW is confirmed by the direct inheritance path of autosomal DNA.
The segmental (via DNA segment triangulation) and total DNA shared between JW and other confirmed descendants of
Jacob K. Patzkowsky/
Elizabeth Penner is consistent with the expected ranges for their respective relationships. Since JW descends from Jacob K. Patzkowsky/Elizabeth Penner through Robin Lynne Willems, the presence of significant shared DNA between JW and other known descendants of Jacob K. Patzkowsky/Elizabeth Penner validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple Jacob K. Patzkowsky/Elizabeth Penner through Robin Lynne Willems to JW, confirming this direct ancestral connection through multiple generations.
