Middle name help!

[tickettoheaven.livejournal.com]

My husband and i are expecting our second daughter in November. We have picked out the name Isabella but can't seem to find a middle name to go with it. Our first daughter's name is Liliana Pearl. I'd really like a middle name that gives the name the same flow, if you know what i mean. Our last name starts with Sh and ends in -man and is three syllables long. Any suggestions are welcome because i am so lost and my husband will be fine with whatever it is as long as it's not Ann or Diane. (His grandmother's and mother's names)
