Freda is an interesting name, I've never heard that before. Eva is very pretty!
I've been thinking about Margaret, that's very pretty and I think "Meg" might make a nice nickname. Not quite sure yet. Yes, my character doesn't fit the steryo-type of "explosive-tempered red-haired person". Most people I've met with red hair (or even red-ish brown or strawberry blond hair even) haven't had fiery temperaments.
Anne is quite nice but perhaps a bit too Anne of Green Gables. I have been thinking of Anna though.
