This was one of my top combos a long time ago, when I started getting into really retro names:
Florence,
Gladys,
Gloria,
Hazel,
Helen, etc. I realized
Gladys needed something to calm its potential dated-ness.
I originally had
Gladys Emma as a combo, but after a while I found the look of it to be off. Then I came up with
Gladys Emily, and it stayed in my Top 10 for a while.
