Godmothers

There was a very fine christening; and the Princess had for her godmothers all the fairies they could find in the whole kingdom (there were seven of them), so that every one of them might confer a gift upon her, as was the custom of fairies in those days. By this means the Princess had all the perfections imaginable.

Godfathers and godmothers don't need to be a couple.

Mary and Helen are the godmothers of my two children, respectively.
