Very sorry to hear about their passing.
I've been involved with handling the 'administrative side' for a few
Wikimedians from the Dutch community we lost last year, and the people that handle the
en-Wikipedia page saw my edits and reached out to me and asked if I could write a small in
memorial about two of them who also were internationally active: the team is quite
pro-active in this. The in memorials were published in the English Signpost.
Also, since a few years Jimmy mentions the people we lost as a movement in his speech on
Wikimania (after an email on wikimedia-l, and maybe other places, to share the usernames
of the people we lost in the past year) and we even had a small memorial site at Wikimania
2019. Very nicely done, under a tree, in the grass field next to the main building.
I guess every community needs to find it's own way in this, the en-wp page is imho a
good point to start if you would like to create a page for your lost ones.
