Matan is also used as a feminine name in modern Hebrew. However, it's more common for males. So, I think that the "Gender" of this name should be changes from "Masculine" to "Masculine & Feminine", and the "Meaning & History" section of this section should be changed to read, "Modern Hebrew transcription of Mattan. It is used as both a masculine and feminine name in modern Hebrew."Sources: https://en.m.wikipedia.org/wiki/Unisex_name https://forebears.io/x/forenames/matan
