Arjaantje

Arjaantje is a Dutch diminutive form of the name Arjaan. Arjaan itself is a Dutch form of Adrian, which is derived from the Roman cognomen Hadrianus, meaning 'from Hadria'. Hadria was a town in northern Italy, which gave its name to the Adriatic Sea. The diminutive suffix '-tje' is common in Dutch to create a more endearing or smaller version of a name.

The name Arjaantje, while clearly feminine due to the diminutive suffix, is quite rare and not widely known outside of specific Dutch-speaking regions or historical contexts. Its usage would likely be found in older records or in families with a strong connection to traditional Dutch naming conventions.
