The maternal relationship between Myrtle Iona Harvill and her son Lloyd Kirkpatrick is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant KU.

The segmental (via DNA segment triangulation) and total DNA shared between KU and other confirmed descendants of Matthias Kelly Harvill/Sarah Burkhart is consistent with the expected ranges for their respective relationships. Since KU descends from Matthias Kelly Harvill/Sarah Burkhart through Myrtle Iona Harvill and her son Lloyd Kirkpatrick, the presence of significant shared DNA between KU and other known descendants of Matthias Kelly Harvill/Sarah Burkhart validates the generational links along this maternal line.

This supports the conclusion that DNA was passed from MRCA couple Matthias Kelly Harvill/Sarah Burkhart through Myrtle Iona Harvill to Lloyd Kirkpatrick, and ultimately to KU, confirming this direct ancestral connection through multiple generations.
