I've always had a soft spot for
Hazel, and don't see it as particularly old-fashioned. I met a toddler
Hazel in a store recently, and the name seemede so charming and fresh.
Your combo is fine, though not really my style.
Hazel Sandrine Adela or
Hazel Margot Delphine would be my version of it, adapting the names but trying to keep the ambiance.
