As a [name_f]French[/name_f], I have never heard most of them.
[name_f][/name_f]Beausoleil and Leclair are masculine, Fontaine or Laruelle would have a s3xual connotation. Chapelle is only one P, very religious. [name_f]Bonnet[/name_f] means hat and is masculine. Binoche, Boudreaux, Brisson, Lavillenie, Bellet, [name_m]Lafayette[/name_m], [name_m]Delon[/name_m], Rondelet, Popelin, would not be wearable. Candelon, Brindeau, Desmairais, Poncelet, Candelon hard to wear for a boy, unwearable for a girl.
[name_f][/name_f]Luneau, Castelot, Delisle, Lorieux, Reverdin, [name_m]Verdon[/name_m], Champlain could probably work for a boy.
[name_f][/name_f]Verany, Tamarelle, Simonet, Savary, Rivière, Ravanel, Manoury, Mandrillon, Madiot, Lémery, Lavanchy, Lamunière, Lalande, [name_f]Joliet[/name_f], Devienne, Deslys, Desroses, Demailly could probably work for a girl.
[name_f][/name_f]Not sure about Verzelen and Margotton.
