I like
Mackenzie Claire. In my opinion, with a three syllable first name the only thing that sounds best is a one syllable middle name. Here are a few examples: Grace,Mae,Rae,Lynn,Anne,Beth. I'm not crazy about
Anne and
Beth but you get my point. I think this is especially true if you have a long last name. That's just my opinion though.
By the way, I don't mind this type of post but it really isn't the function of this board. This message board is mostly supposed to discuss the history and meaning of names. I think you'd get more replies to your question if you went to
www.babyzone.com, went to the site map, clicked onto the baby zone message boards and went to the Baby nameing section.
Good luck with finding a name!
