Tilly

Tilly is a girl's baby name of German origin, a diminutive of Matilda, from the Old Germanic Mathilde, composed of maht (might, strength) and hild (battle), meaning "mighty in battle." As a nickname name, it carries vintage British charm.

Tilly has been one of the more beloved revival names in England and Australia, where it consistently ranks in the top 50. In the United States, it has been growing as parents discover its old-fashioned sweetness — the kind of name a great-grandmother might have had, perfectly charming for a 21st-century child.
