middle name possibilties

[deathofrats.livejournal.com]

I really like the name Harmony but am stuck on middle names for it. It has to go with the last name Mallon. My first daughter's name is Sabrina Isis Renée. I have two middle names as does my father and his entire family but I may be the first to stop it (why not? what is the point of two middle names anyhow?). Any ideas on Harmony followed by either one or two middle names?
So far all I've got is Harmony Rae Cenedra (Cenedra is from the Wheel of Time series). I also really like the names Daphne and Celeste so could also drop Harmony and go with one of those instead.
