Family member not shown in "Find My" widget

I have absolutely no experience with the new widgets but would suggest:

Sometimes it helps to have the devices involved take a fresh look at settings:

- Try signing out of accounts and back in again.

- Restarting is a simple step that can resolve many unexpected behaviors.

If a problem persists, particularly over several days, try contacting Apple for assistance:

Click here --> Choose your country or region - Official Apple Support Select your country, then a product. If you don't see one that handles your issue then keep experimenting with selections until you reach one that gets you a chat session or a telephone call and get the representative to redirect you.

or:

"See a list of Apple phone numbers around the world."

Click here --> Contact Apple for support and service - Apple Support

I can't even use widgets on my computer (well, I can but they are the ones from 2012).

The only Apple document I can see relating to this is Use Find My widgets in Notification Center - Apple Support

but it doesn't go to your level of specificity. From the little it says i would think you could since it says "people", but you may need to ask Apple about this.
