Besides Christine, I would have changed it to either:

• Alexandra (or Alex for short)
• Alice
• Allison (or Ally for short)
• Aubrey
• Autumn
• Cadence
• Cameron
• Charlotte (or Lottie for short)
• Courtney
• Emily
• Evelyn (or perhaps Eve for short)
• Gemini
• Genevieve
• Grace
• Haven
• Jennifer (or Jenny for short)
• June
• Katherine (or Kathy for short)
• Luna
• Rebecca
• Storm
• Summer (my "second" choice according to my parents, since my Vietnamese name means Summer, though they were downright firm that they were going to name me Christine, like "we're naming our baby girl Christine, end of story, LOL!)
• Sydney
• Winter (very contradictory and ironic because I was born in the summertime).
