If DC2 is a girl, we are set on using a form of Catherine as a middle name for sentimental reasons. We very much like Catherine as it is, and also like Katerina.
We both love Jennifer as a first name, but I'm not convinced by 'Jennifer Catherine' - I don't think it flows, especially once you tag on both of our long surnames (the DCs are mixed nationalities, and we use both names for legal reasons). Jennifer Katerina is even worse!
Even if we don't settle on Jennifer, I'd love to come up with some alternative forms of Catherine. Help!
