Haha, one of my great grandmothers was called Bertha. The others were Martha, Martha and Hertha (which is also the name of my town's football team). All those sound sort of the same.
My first name, Susanne, is okay, at least the way English speakers pronounce it.
Middle name #1 is Gudrun. It's my mum's name. I don't like it.
Middle name #2 is Elisabeth. It's my mother's mother's name. It's good.
Middle name #3 is Thea. That's my father's mother's middle name. Her first name is Inge which is apparently hard to pronounce. Thea is my favourite of the four in German pronounciation. I have trouble remembering how it's pronounced in English.
I think I'm gonna give all my children Welsh/Irish names and Greek middle names. Arete is awesome, but only as a middle name.
