I also have a French DH and we live in the UK. We have a DS and expecting a DD. We know lots of bilingual families. As a general rule I think the "classic" names work best as they're well known in both countries/languages and easy for both sides to pronounce.
Mathilde (Tilly) - ok
Maeva (Maeve) - don't think the French will get on particularly well with this
Emeline - isn't it Emmeline?
Florence - love (def my fave from your list)
Elodie (Edie) - like Elodie but not Edie, there are loads and I dislike the trend for old fashioned names in general and Edie in particular
Cecile - too French for my taste
Hugo - pronounced very differently due to the H, I would avoid
Miles - fine in English but doesn't work at all in French, they'd probably pronounce it "mille" as in 1000.
My suggestions:
Girls (although I do love Florence from your list)
Adele
Clementine
Emma
Louise
Mia
Sophie
(Oh and I'm not a fan of Manon, btw, I think it sounds rather ugly.)
Boys:
Adam
Leo
Max (I like Maxim as a longer name)
Noah
Tom (Thomas)
Personally I'd avoid any name with "th" (eg Nathan, Theo) because I don't like the different pronunciations, I'm fluent in French but as a native English speaker I find the hard French "th" too harsh and ugly when it's in a name I'm used to hearing with a soft English "th".
