[Mum8]

Which one do you like more?
Clara or Greta?
Clara keep thinking about, in our list for a while. Greta a new idea,but someone I know only at work used it. But I find it sweet. Clara we will pronounce like Tara and Greta with e as in men and a soft t in ta. Will either work in the UK? We are not German btw, though one of DH's ansestors was German.Our last name is a Spanish one.

Greta. I don't like the 'khlar' sound of Clara

Same. I can't hear Clara as a pretty name at all.

Greta or Gretal

Clara. Great also makes me think of witches!
Clara with Greta as a middle name is awesome
