Hazel (middle name TBD) - help!

Jennifer
We are thrilled to have another girl! Our first born is Harper Sofia.
We decided on Hazel. Can't finalize a middle name. A few I like are Quinn, Ava, Ann.....
My husband lost his twin brother to a brain tumor a year ago and wants to cordinate his name, Tom (Thomas). I don't hate the idea since we probably won't have another baby.  We just can't think of something that would work. 
Thoughts?
