Baby Name Poll Results

My sister passed away the day before yesterday after a hit and run accident leaving her son Alexander Orion 3 and newborn daughter, both of whom I’m adopting with my husband as was a single mother. My dearest niece is left nameless and for sure will be named Katherine ??? after my sister but I don’t know what middle name to give her. We’ve decided to give her a constellation name like her brother rather than Isabelle because we want them to share a link. They’ll be joining my twins Victoria Adelaide and Alexandra Elizabeth. Please help us! Thanks a lot! Annie and John.
