Oh my goodness! I am sorry for the family loss, that is tragic.
In that case, you want to let geni know through the help function, so they can release the account and associated profiles to his closest relative on geni. Use the Help link at the footer to open a case or sometimes it's just easier to use help@geni.com.
If claimed person (Geni user) is now dead then his/her immediate family member (also claimed person (Geni user)) shall contact help@geni.com about this. Recommended action - to take over management of all these profiles. Bad example - to delete all this profiles...
If nobody in family wants to take over these profiles - some of Curators will do it.
