Yeah I think you have the record. That’s insane. When my great grandfather died my grandfather was 77, my uncle was 53, and my cousin was 22. Seems insane but it happens. My great grandfather also lived to see his step great great granddaughter’s birth (he died 5 months or so later though), nobody else in here has mentioned great great grandparents that so I think that may be the generational record.
My paternal grandmother was the last of mine, and she died in her early 80s when I was in my 30s.
My maternal grandfather died when my mom was a kid, so I never knew him. My maternal grandmother died when I was 14; my mom was on the younger end of a large family, and Grammy was in her early 80s when she died (I’m almost 50 now).
My paternal grandfather died in his early 80s when I was in my late 20s.
I’m sensing a pattern here; somehow I never noticed that before, but the last 3 were all around 83.
