I only manage profiles of people that are either blood relatives or their spouses, so if you see my name on a profile I'm related! (There are a handful of exceptions) I Manage 2,817 profiles as at 1 January 2021.
Of course some of my blood relatives are managed by other people as well.
I do a lot of edits as part of the Data Doctors project, so I'm not just editing my relatives.
