Line 5 of the Honor Code that everyone has to sign in order to enter information here:
We respect privacy. We privacy-protect anything we think our family members might not want public. If that's not enough for someone, we delete their personal information.
So if it truly is creating an issue with a living family member and they do not want their information here - you can first privacy-protect the profile so that the information can't be viewed by anyone but the family member, and then if that is not enough, you can ask for the profile to be removed.
