I've already posted on here looking for boys' names that are pronounced similarly in both English and German (DH is German, we live in Germany).
What do you lot think of Ferdinand? I think Ferdy is quite sweet as a nickname.
Other names we like (although the first two aren't pronounced the same in the two languages ...):
Arthur
Jonathan
Alexander
Other names I like that DH has vetoed:
Sebastian
Rueben
Tristan
Christian
Thomas
