The maternal relationship between Ella Tesch and her son
Gerald Doree is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant RD.
The segmental (via DNA segment triangulation) and total DNA shared between RD and other confirmed descendants of FH is consistent with the expected ranges for their respective relationships. Since RD descends from FH through Ella Tesch and her son Gerald Doree, the presence of significant shared DNA between RD and other known descendants of FH validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA FH through Ella Tesch to Gerald Doree, and ultimately to RD, confirming this direct ancestral connection through multiple generations.
