Anne Bledsoe (UNKNOWN-159906) and Mary Washington (Ball-463) are father's only sisters, Anne's mother is yet unknown.
Connection Finder says Anne is 1 Degree from Mary: Mary is the sister of Anne.
But, Mary is 2 Degrees form Anne: Anne is the daughter of Joseph Ball, and Joseph is the father of Mary. (This also should be a 1 Degree connection: Anne is the sister of Mary).
Stange, isn't it?
