Letje is in Origin.

Letje is a Dutch diminutive formed with the suffix -je, used as a familiar name for Lette, Alette, or Aletta - short forms ultimately going back to the Germanic Adelheid, “noble kind.” In some families it also shortens Letitia/Leticia, from Latin Laetitia meaning “joy, gladness,” so the name may carry either a “noble” or “joyful” sense depending on its source.

In the Low Countries, Letje surfaces sporadically in 17th–19th‑century parish records, mirroring the popularity of Aletta (cf. physician and reformer Aletta Jacobs). Today it is rare as a legal given name and more typical as an affectionate byname, though vintage diminutives are seeing a quiet revival. Variant spellings and relatives include Letty and Lettie (English), Lette and Letta, and the longer forms Aletta/Alette; cognates tied to the same roots are Adelheid/Adelaide and Letitia/Leticia/Letizia.
