I love that it's such a crochety old sourpuss of a name and it has the word "glad" in it.
In some ways it's kind of odd that it's so clunky, because it's really a very open, breezy and light name. It's got the very feminine "iss" ending. I guess it's the rather ponderous "Gl" opening that weighs it down.
Some combos! I generally pair
Gladys with things that are genuinely light and frothy.
