Hanoch Teller has a story about a woman who he thinks was a Gilgul of the Chafetz Chaim. I don’t remember where it was, though. It was because she made a huge campaign for Shmiras Halashon and she lived for 27 years, which adds up to 120 with the CH”CH.
There is a statement in the Mishnah B’rurah that a woman cannot be a Gilgul of a man.
