An existing, but very uncommon, name in Sweden is Josabeth. I've met one woman by that name, and most people have never heard it and believe it to be made up when they do. But it is quite old, and there was a painter in Stockholm, Madame Josabeth. There's a set of stairs named after her in Stockholm.
My mother's name is Josephine Elizabeth and she's been "JoBeth" her whole life. So, to me it's not a weird name at all. It's just like a Mary Jo or JoAnne.
