Tilly

Tilly is a diminutive or pet form of the name Matilda, which is derived from the Germanic name Mahthildis. This name is composed of two elements: 'maht' meaning 'might' or 'strength' and 'hild' meaning 'battle'.

Matilda was a popular name among the nobility in medieval Europe, and it has been borne by several royal figures, including Queen Matilda of England, wife of William the Conqueror.

The name Tilly emerged as a shortened, more casual version of Matilda, and it has been used as an independent given name in English-speaking countries since the 19th century.

Tilly is a friendly and approachable name that is still relatively uncommon, making it a distinctive choice for parents looking for a name with historical roots and a strong meaning.
