Ooh, both are so pretty! Honestly, Ruena Leonne has a nicer flow to me, it sounds more elegant and less common, while Ruena Cassandra feels a bit heavier together. A few of us mums were talking about baby names last week, and one of my friends said she chose her daughter's middle name based on how it sounds when you say the full name out loud, so try saying both a few times and see which one feels right to you, mommy! What's the story behind these names, do they have family meaning?
