The
Dutch forms of
Noah are
Noach or
Noë. Neither are very popular. Since the 1990s
Noah has been heavily used, just as it has throughout
Europe (especially northwestern
Europe).
The
Dutch feminine form, reaching the top 10, is
Noa. This is ostensibly the unrelated biblical woman's name
Noa, listed as Noa(1) on this site.
Noé would probably be more accurately considered a variant of it, so would properly be a separate name entry. I have undeleted the
Noé submission you made several years ago.
