Surnames are not one system but many, and each tradition encodes something different. Patronymic systems name the father: Scandinavian -sen and -sson, Slavic -ov and -ovich, Irish Mac and O', Hebrew ben. Toponymic systems name a place, which is where many French and English surnames beginning with de, van, or von originate. Occupational surnames name a trade — the Smiths, Schaefers, Fabres, and Kovacs of the world all descend from the same handful of jobs.

Others work differently again. Spanish and Portuguese traditions commonly carry two surnames, from father and mother. Many East Asian traditions place the family name first, before the given name. Knowing which system you are drawing from is the difference between a surname that feels real and one that feels assembled.

The most common mistake in fiction is a surname that fights the given name. A first name from one tradition and a surname from another can be entirely realistic — that is what migration and marriage produce — but it should be a deliberate choice rather than an accident, because readers notice the mismatch and will assume it means something.

Beyond origin, consider era and register. Some surnames read as old money, some as rural, some as recently arrived. A character called Pemberton carries different assumptions than one called Kamara or Novak, and those assumptions are part of your characterisation whether you intended them or not.

There is a useful trade-off between common and distinctive surnames. Very common ones — Smith, Ivanov, Nguyen — feel authentic and unremarkable, which is right for background characters but can make a protagonist hard to remember. Rarer surnames stick better, at the cost of standing out slightly more than a real person's name might.

If you are writing contemporary fiction, using a real surname is normal and expected. If you are naming something public-facing such as a brand or a pen name, it is worth a quick search first to see who already carries it.
