The maternal relationship between Lillian Christie Chambers Curran and her daughter
Jean Chambers Curran Donley is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant PCD.
The segmental (via DNA segment triangulation) and total DNA shared between PCD and other confirmed descendants of
John Gilbert Chambers/
Mariannne Marion Mary Anne Veronica McDermott is consistent with the expected ranges for their respective relationships. Since PCD descends from John Gilbert Chambers/Mariannne Marion Mary Anne Veronica McDermott through Lillian Christie Chambers Curran and her daughter Jean Chambers Curran Donley, the presence of significant shared DNA between PCD and other known descendants of John Gilbert Chambers/Mariannne Marion Mary Anne Veronica McDermott validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple John Gilbert Chambers/Mariannne Marion Mary Anne Veronica McDermott through Lillian Christie Chambers Curran to Jean Chambers Curran Donley, and ultimately to PCD, confirming this direct ancestral connection through multiple generations.
