Reply To: Names that are used for both boys and girls

Interestingly, Simcha is used by Ashkenazim for boys and Sefardim for girls.
Are you counting modern Israeli names as “Jewish names”? If so, there are many- the trend among secular Israelis is to use these “neutral” names, often taken from nature- like Tal.
Joseph, I suspect that names like Tzviya (or Tzivya) and Yosefa originally came about in that manner.
