We were talking about silver-age Sue Dibny's theoretical family money in another thread. And it got me to thinking - at the age she married it was likely that she and and Ralph not only had parents, but also grandparents still living (and the bulk of family money tends to be in the hands of the oldest generation).
While obviously age of first marriage and children have gone down and up over the years, many of these heroes were still in their 20s when they donned the mask and/or cape. Seems statically some of them would have some grandparents still living when they became heroes. I'm not talking about Wally, who was teenager and had Ira, but instead the adults. I know they aren't likely to be plot-relevant, but can you think of any that mentioned living grandparents? That had grandparents show up in wedding or holiday scenes? Anything like that?
It doesn't actually matter, I was just thinking about it.
