I don't have views on
Menashe but I do on
Freyde. It reminds me of
Freda, which I don't think is attractive. If you're honouring someone, that's a different matter.
I much prefer
Aliza, the Israeli/Hebrew equivalent of
Freyde.
My favourite Yiddish girl names are
Shaina or
Shayna (prefer the y version) and
Shaindel or Shayndel (again, the y version is my fave).
