Same with "Ngo", listed as the most common name in Cameroon. Technically not a name, it just means "the daughter of" and is only common with one of the many tribes that populate the country.

The Most Common Last Name in Every Country

Hello, this is kumar speaking!

I don't like 'Devi' being listed there, but for a different reason. I take it as a lack of domain knowledge.

I don't like it because I don't consider 'Devi' as a last name or surname, although technically it is.

In India, when you know a girl is married and a little old, you don't want to call her by her first name, you add devi after her first name to show respect. Though in big cities people don't follow it.

I suspect the data might show 'Devi' as the most common last name because, when married women from villages registered for an Aadhar card (similar to a Social Security Number) over the last 20 years, the person assisting them invariably added 'Devi' as a last name.

Footnote:

'Devi' means Goddess.
Kumar is also not 'technically' a last name
