T1's nephew committed suicide and I heard about it from another source. Actually I knew the nephew was having some major issues because a woman I was in Bible study with for a year was good friends with the nephew's mom. So I would get weekly updates and of course I prayed for him. I put it together because T1 asked about my experience with Malaria preventing drugs (which was bad) and mentioned that his nephew was struggling. So for quite a while I was getting weekly updates about the nephew including some pretty strange behavior but I didn't say anything in therapy. It didn't really pertain and I am not in the habit of sharing stuff like that anyway.

So when the nephew suicided I got a call from the church member asking for prayer for the family. Soon after I was in t's office and he said that he was having a really bad day and I could tell he was struggling to keep it together. I decided to just tell him that I knew about his nephew. It wasn't a real productive session, but I did learn about grief and how much it affected family members, Which was helpful in my own struggle with ideation.

T3 would never give me the info so that I could make the connection in the first place.

I can see the benefit in both sides.

And, I think if I were OP I would give to the family if I wanted to. I might use a different email address, but it only takes a minute to sign up for a hotmail or yahoo account.
