The maternal relationship between Marinda Jane Headlee and her daughter
Elizabeth Jane Snodgrass is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant DW.
The segmental (via DNA segment triangulation) and total DNA shared between DW and other confirmed descendants of
William Jarvis/
Elizabeth Dillon is consistent with the expected ranges for their respective relationships. Since DW descends from William Jarvis/Elizabeth Dillon through Marinda Jane Headlee and her daughter Elizabeth Jane Snodgrass, the presence of significant shared DNA between DW 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 Marinda Jane Headlee to Elizabeth Jane Snodgrass, and ultimately to DW, confirming this direct ancestral connection through multiple generations.
