Which middle name? (Please read)

Marlowe is our last name.

I wanted to go with Emerson Sage because our other daughter’s middle name is Rose. I felt that Sage and Rose as middle names went together really well and flowed nicely.

My older sister recently passed away. Her name was Skye.

Does Emerson Skye flow well and sound okay with our last name? Does the middle name fit my other daughters middle name?

Sorry, my thoughts are a little all over the place... this was very sudden and I’d like to use Skye, but I was so sure about Sage that I’m unsure what to do now.
