Baby Name Poll

We are in the process of adopting one of our foster children. Her name is McKenna, she is eight and we have had for a little over two years now. She does not have a middle name, so we asked her if she wanted one. She said "Yes, but I don’t know what." Some she has come up with herself are: Bailey, Robyn, Summer and Lilly. We were fine with whatever she decided on, but she recently asked us what we liked and, truth be told, we hadn’t thought of it much (we’ve never had the blessing of naming a child before). So, we told her we’d think about it, and that she should keep thinking about names that she liked too. Once we have a list of some we like, then we’ll see if she likes any. So, I was wondering if I could get some help coming up with some middle names as I’m not really sure what "flows" or "sounds good." Does any name work as long as you like it? Help please?
