The paternal relationship between William Fleeman and his daughter OF is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant TA.
The segmental (via DNA segment triangulation) and total DNA shared between TA and other confirmed descendants of
John A Brogan/EB is consistent with the expected ranges for their respective relationships. Since TA descends from John A Brogan/EB through William Fleeman and his daughter OF, the presence of significant shared DNA between TA and other known descendants of John A Brogan/EB validates the generational links along this paternal line.
This supports the conclusion that DNA was passed from MRCA couple John A Brogan/EB through William Fleeman to OF, and ultimately to TA, confirming this direct ancestral connection through multiple generations.
