Need Help with Middle Names

My husband and I have been trying to get pregnant since October 2015. We're deciding to play with and choose some names while waiting. :) We have narrowed it down to one boy and one girl name but now the difficult part...we need to find middle names to make it flow. Everything we have come up with is cluncky. Avayla ____ Swain for a girl.

Arlo ____ Swain for a boy. Obviously we like unique names. I like the idea of a one syllable name. If you have any ideas at all I'm more than willing to listen. Thank you!
