The My Cousins feature https://www.wikitree.com/wiki/Special:MyCousins is excellent because it is an easy way to see which of my living relatives (as distant as 6th cousins) have DNA tested. Is it possible to do the same for my mother (or father)?
Found the answer from 2021: "... only sysops can view other profiles' MyCousins at the moment."
