Seynlis is in Origin.

Seynlis is a rare, modern French-tinged given name likely linked to the toponym Senlis, a medieval town north of Paris, or coined from Seine + lis (“lily” in French). It blends a place-name aura with the fleur-de-lis, yielding interpretive meanings such as “from Senlis” or “lily of the Seine.” Senlis itself traces to Latinized forms tied to the Gallic Silvanectes, lending Seynlis an ancient Gallo-Roman undertone.

As a forename it surfaces only in recent records and reads as unisex, in France and abroad; earlier occurrences are locative surnames (de Senlis) among clerics and nobles. Variant spellings include Senlis, Seinlis, Seynlys, and Seinlys; short forms Sey and Lis are natural. The -lis/-lys ending places it near chic French-adjacent choices like Anaïs and Élis, with connotations of purity and understated elegance.
