All your names have so much zing I would immediately eliminate the more common/acceptable [name_f]Flora[/name_f], [name_f]Willa[/name_f] and [name_m]Silas[/name_m].
From your list I agree with earlier comments about name similarities and would thus choose [name_m]Amos[/name_m] or [name_m]Magnus[/name_m], [name_f]Margit[/name_f] or [name_f]Leonora[/name_f] (love!)
Alt suggestions:
[name_m]Sylvester[/name_m], [name_m]Ivor[/name_m], [name_m]Ragnar[/name_m]
Margali, [name_m]Wren[/name_m], [name_f]Agnes[/name_f] or even [name_f]Ines[/name_f] (ee-NESS prn)
