Maartje

Maartje is a Dutch feminine diminutive form of the Latin name Martinus, itself derived from the Roman god of war, Mars, whose name may connect to an older Indo-European root meaning "to gleam" or may simply denote the god and his martial associations. The name entered widespread use in the Netherlands as an affectionate and familiar form, carrying the warm, informal character typical of Dutch diminutives ending in -je. It shares its ancestry with Martha in some folk etymologies but is more directly linked to the Martinus line, making it a cognate of names such as Martina, Maarten, and Martin.
