That specific profile and the wife is without any dates, not even estimated, marked private even if marked as deceased.
However, as you tell, and which Leanne probably did not check, you are correct about the daughter, which by the way is a public profile, so keeping the parents private makes no sense anyhow, except if it is because the manager are uncertain about them, so if you could help adding dates or correcting to the profile that would be of big help.
