Names!!

So we have the first name picked out but we are having trouble with the middle name.

We have four very wonderful women that we would like to name a girl after but... it's difficult to combine them.

First name is going to be Octavia.

We have two Shannons, a Kay, and a Lynn.

DH doesn't like just Shannon for middle name, and I don't like kaylynn. Are there any combos that you like or see or prefer one name over another?
