I love how
Ada sounds in English, even though I dislike it in my native language. I have a slight preference for
Adelaide nn
Ada, but it works well on its own. I don't think it would get confused with
Ava. Jann is jarring,
Mary is lovely,
Claire and
Annette are dull. My choices would be
Adelaide Mary Jann and
Adelaide Claire Annette.
