This uncle...living or dead?
If dead, when?
Record of strength of relationship?
Haven’t come across those details. I had the impression the uncle was dead. No idea when. Not certain either way. No details about strength of the relationship. My impression was connected but probably not super close. OK OK. I’LL duckduck it.
