What Makes a Last Name “Rare”?

Before you can answer what the rarest last name is, you have to understand what “rare” actually means.

A surname is considered rare when:

only a few people carry it
it exists in a small geographic region
it has unusual spelling
it came from a small family line
it was changed through immigration
it has died out over generations

Rare Doesn’t Always Mean “Cool”

Some rare surnames are rare because:

the family line ended

records were lost
people adopted new surnames for safety or social reasons

So rarity can come from history, not popularity.
