Conundrum

The above word is "a paradoxical, insoluable, or difficult problem; a dilemma." I'm having quite a time trying to find a title (and thus, a name for a central character) for a short story I've come up with; why do girls have to be at the center of every guy's problems? It needs to be a name that isn't totally out of place in modern times, but alternately isn't a name that gets heard a lot. Also, for a variety of reasons, I don't want it to be the name of any girl I know. These are a few of the ones I'm considering, plus their meanings:

Lenore--"Light"
Leslie--"Meadowlands"
Lianna--"My God Has Answered"
Lorene--"Small Victories"
Lucinda--"Beautiful Light"
Sabrina--"Princess"
Selena--"The Moon"
Serena--"Serenity"
Siobhan--"God Is Gracious"
Deborah--"Honey Bee"
Desiree--"Desired"
Diana--"Divine"
Dorothy--"Gift of God"
Dulcinea--"Sweet"
Theresa--"Harvester"

Be seeing you,
Steven
