Mersilla is in Origin.

Mersilla is a rare feminine name with layered, possibly blended origins. Its structure fits Romance diminutive patterns (-illa), suggesting ties to Spanish or Italian naming. One line links it to Mercilla - an allegorical figure named by Edmund Spenser, derived from “mercy,” thus giving Mersilla the meaning “compassion” or “grace.” Another connects it to the Marcella/Marsilia family (from Latin Marcellus, ultimately “of Mars”), yielding the alternative sense “warlike” or “dedicated to Mars.” A toponymic echo of medieval Latin Marsilia/Massilia (Marseille) is sometimes noted but remains speculative.

Usage is sparse and modern, appearing occasionally in Hispanic and Anglophone contexts as an inventive, mellifluous choice. Variants and near-forms include Mercilla, Mersilia, Marsilla, Marsella, Marcella, and Marisela/Marisella. Possible short forms are Mer, Miri, Silla, or Sila. With dual interpretive meanings - “mercy” or “of Mars” - Mersilla offers a distinctive, culturally versatile option with poetic resonance.
