Okay kiddo, a last name is like a special name that you and your family share. It's kinda like a team name for your family!
Laird is one of those last names that some families have. It's usually passed down from a person's dad to their children, and so on.
Laird is also a word that means "lord" or "landowner" in Scotland. So some people with the last name Laird might have had ancestors who were important in their community or owned a lot of land.
But, just because someone has the last name Laird, that doesn't necessarily mean they're Scottish, important in their community, or landowners. It's just a last name that some people have!
