It's normal to grieve the death of someone you didn't know. Often, especially if they are a family member, we can find similarities and bonds, even if you've never met. Sometimes, when a family member we've never met dies, you can start thinking of how you never met them, and now you'll never have a chance, which can also cause grief, in my humble opinion. Everyone is different when it comes to reacting to death.
