I think it will come back - Tilda, Matilda and Gilda are all fine, and it will be too. It is an 'old lady' name, bu that in itself isn't a problem: there are a lot of lovely grannies/aunties which give positive associations.
Corrie characters do, of course have an impact (would anyone really have an Audrey, Gail, Deirdre, Bet, Hayley, Vera, Ivy etc?).
