My fellow Americans, how many of you had great grandparents that were alive when you were born?

None of mine were alive when I was born since the youngest of my great grandparents would have been 92 and the oldest was born 111 years before me. This is partially due to having older parents(42,35) and paternal Grandparents(81,80) when I was born but even with slightly younger maternal grandparents when I was born(69,67) I had no chance of meeting any great grandparents because many of them didn’t make it past 70 or have the luck to make make it past 90.
