That sounds like a nice moment.
It's getting increasingly rare for families to all live and die in the same spot, so I'm guessing that some of these family plots with many generations will get increasingly rare.
That said - on my maternal grandmother's side, we have a plot with both grandparents, my mom's first child (born alive, died a few hours later), my brother, my aunt, and my mom. My mom and brother were both cremated, so that left extra space. There is a plot for my still-living uncle. It is nice to see the family history there, even though that 3-generation space doesn't really go that far back.
My dad's family also has a multi-generational plot, and that tells quite the story of immigration, national service (dad served in WWII and his rank is on the tombstone), and family tradition.
