Pregnant with triplet girls, which names sound best?

I am due in july 1st and I need help with some names for my triplet girls (: I am 26. I have two boys ages 2 and 4, they are named issac and dylan so I want my daughters names to kind of fit in with theirs. So far I love these names: Lacey, Samia, Milan, McKenna, Klien and Sydney! But I am having a hard time narrowing it down to just three so if you have any recommendations let me know please and thank you!
