I guess it depends on who or what you consider family. You have your immediate family members and non-immediate or extended family members. Immediate family is your wife/husband, the kids, brothers, and sisters. Extended family is everything from cousins, uncles, aunts, etc.

None of my non-immediate family members knows about my interest in bitcoin. And there is no reason why they should know. It's not that I don't trust any of them, but my interests and theirs are completely different. My immediate family, of course knows. Someone needs to inherit my assets and possessions if something were to happen to me, so I have no regrets on that front. I hope you didn't make a mistake choosing your spouse.

When it comes to friends, I categorize them in different groups depending on how close we are.
Those who are really close know about my work with bitcoin and crypto and there are no problems there. They have been vetted thoroughly though to belong in a close circle of trust.

Keeping your seed in geographically different locations is highly recommended. Look at the devastating earthquakes that hit Turkey and Syria last week. Now imagine that if by a stroke of luck you survived, but everything you owned got destroyed together with your apartment building. All your crypto assets are gone and somewhere in the rubbles because your backups were in the same location. But maybe just maybe you could have kept a copy at your parents or grandparents house who live hundreds of kilometers away.

That's true, but that's also one reason why you should keep your real identity separate from anything that can be connected to your bitcoin wealth.
