I would be so delighted to hear of a baby girl [name_f]Hilda[/name_f]! I think it’s adorable and ready for a comeback, either on its own or as a nickname for Matilda/Mathilda.
I love [name_f]Hilda[/name_f]! She is sweet, strong , charming, and spunky with a big personality.
Come to think of it- While I know one [name_f]Hildy[/name_f] (mentioned up-thread), I actually know a whole bunch of girls and women named [name_f]Hinda[/name_f], nickname “Hindy,” which sounds second nature to my ears.
