Which one? Breea or Brinley for baby girl?

I am trying to find a name for my little girl due in August (although she will probably come sooner!) I just found out last week (finally) that we are having another girl! I already have 2 beautiful little girls. My oldest is Nevaeh Leigh and my yougest is Legna Grace. (nu-va-uh) and (L-e-na) I really like the name Brinley and I also really like the name Breea! I want to pick between these two names and need some help! Also we thought about carrying on my mother in laws name (Sara) as the middle name but it doesn't seem to fit. If I can't get it to work I just won't use Sara. Please help me pick out a name for this baby... my husband likes both as well. Got any cute middle names?
