I think that kind of depends on what her father's journeys were like, Lucian has worked pretty much exclusively out of French territories and he would probably be somewhat reluctant to deal with German men after the war, but it's not exactly impossible if you have some ideas in that regard!

I think her father is highly pragmatic man, and has no qualms about hiring or working with the most qualified people, regardless of nationality. Ultimately it is up to you, Lucian is your character after all, I just had a suggestion :)
