Hm, the first thing that comes to mind is one Russian tongue twister,
Карл у Клары украл кораллы, Клара у Карла украла кларнет
(something like "Karl has stolen (the) corals from Clara, Clara has stolen (the) clarinet from Karl"... it's more difficult to pronounce it in Russian of course).
Lea sounds much better to my ear, but I'm not a native English speaker and I'm not sure if it is a common name. Sounds really nice, though.
