Depends on what you consider "filled". Most people or their living relatives saw some sort of action. But in many cases it was once-in-lifetime happening. On top of that, a big chunk of medieval wars were meet-you-in-a-field-out-of-town kind of affairs.

As for royal vs. peasant.. big chunk of "blue blood" royalty had genetic diseases thanks to intermarriage to keep pure blood.. Meanwhile peasants knew it's not good to marry exclusively inside of a village and tried to spice things up by mixing with neighbouring villages.
