Biblical name. Not the same name as male name.
Acc. to Wikipedia: "Michal" was one of the Biblical names embraced by Zionism, very rarely found in pre-Zionist communities. It is a very common female first name in contemporary Israel.
Polish popular male first name "Michał" is a local form of "Michal".
מיכל not the same as the Hebrew for Michael of course. מיכאל
