The maternal relationship between Eleanor Jarvis and her son WDG is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant DM.

The segmental (via DNA segment triangulation) and total DNA shared between DM and other confirmed descendants of William Jarvis/Elizabeth Dillon is consistent with the expected ranges for their respective relationships. Since DM descends from William Jarvis/Elizabeth Dillon through Eleanor Jarvis and her son WDG, the presence of significant shared DNA between DM and other known descendants of William Jarvis/Elizabeth Dillon validates the generational links along this maternal line.

This supports the conclusion that DNA was passed from MRCA couple William Jarvis/Elizabeth Dillon through Eleanor Jarvis to WDG, and ultimately to DM, confirming this direct ancestral connection through multiple generations.
