The maternal relationship between Ann LAUNDON and her son
Edward ROBERTS is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant Joan Patricia ROBERTS.
The segmental (via DNA segment triangulation) and total DNA shared between Joan Patricia ROBERTS and other confirmed descendants of
William LAUNDON/
Mary LEE is consistent with the expected ranges for their respective relationships. Since Joan Patricia ROBERTS descends from William LAUNDON/Mary LEE through Ann LAUNDON and her son Edward ROBERTS, the presence of significant shared DNA between Joan Patricia ROBERTS and other known descendants of William LAUNDON/Mary LEE validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple William LAUNDON/Mary LEE through Ann LAUNDON to Edward ROBERTS, and ultimately to Joan Patricia ROBERTS, confirming this direct ancestral connection through multiple generations.
