Cecelia Phillips

The maternal relationship between Cecelia Phillips and her son William Urmson is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant PGI.

The segmental (via DNA segment triangulation) and total DNA shared between PGI and other confirmed descendants of TP/MJ is consistent with the expected ranges for their respective relationships. Since PGI descends from TP/MJ through Cecelia Phillips and her son William Urmson, the presence of significant shared DNA between PGI and other known descendants of TP/MJ validates the generational links along this maternal line.

This supports the conclusion that DNA was passed from MRCA couple TP/MJ through Cecelia Phillips to William Urmson, and ultimately to PGI, confirming this direct ancestral connection through multiple generations.
