I don't really care for it myself. I too like simple, strong names, but
Lee is a little bland for me. And I must admit it does conjure up one image for me - but then, I am just one person.
But if you love it, more power to you! I guess for combos, you'd have to specify what sort of look you are going for, or what style of names you enjoy - classic, exotic, old-fashioned, popular?
Some combos that immediately popped into my mind were:
Lee Anabelle (the old switcheroo!)
Lee SeraphineLee ClementineLee VioletteLee JessamineLee GabrielleLee AngelineLee EmmelineLee RosalineLee IsabelleLee Madeleine
Lee BarnabasLee AugustineLee MalachiLee GabrielLee BenjaminLee ElliotLee FrederickLee Harrison
