Whats in a name?

I'm asking all 4 of my loyal readers to help.  We are having problems coming up with a name for baby #4.  Reagan Marie was agreed on very early.  Before baby #2 came, Brooke said she wanted to name our next kid Baylor.  Once we found out we were pregnant, I soon picked Grace as her middle name.  So for about 7 months baby #2 was Baylor Grace.  The problem was I have loved the name Caroline.  Since I hadn't a whole lot of say in picking names, one night at my parents house I said "Babe, (referring to Brooke) I really love the name Caroline. Can we call baby #2 Caroline?"  Much to my surprise Brooke was okay with that on the condition that our next baby would be Baylor Grace.  It worked out well too because in our minds Caroline is such a Caroline, and baby #3 totally is a Baylor Grace.  This brings us to our current "problem."  We cant pick a name for baby #4.  I like Savannah, Brooke does not.  She likes Hadley, I'm not thrilled with it.  We both sorta like Charlotte, sorta like DeLaney.  In reality nothing is sticking.  So, I am asking my faithful followers for help. What should baby #4 be named.  My Mom and Dad suggested Kennedy Michelle.  Kennedy for my middle name, Michelle for Brooke's.  That would be great, except we already have a Reagan. We cant have a Reagan and a Kennedy, just as we wouldn't have a Jackson and a Grant.  So we are stuck.  What are your thoughts, help us name baby #4!
