If I like Beatrice and Iris....

[birdssuddenlyappear]

.... but can't use them as they sound silly with our surname, which ends in -is, which names are similar?

I like them because they are pretty, quite traditional, I think will suit both a child and an adult, I also don't hear either of them too commonly.

Any suggestions?
