What is my great-grandfather’s female cousin to me?

Is she my great-aunt? My “something”-cousin “something”-removed (Like third cousin twice removed)? I want to know because she was pretty famous, so I wanna be able to tell the story correctly. Thanks!

If they are first cousins, then your shared ancestor is your x3 great grandparents who are their grandparents, so 1st cousins 3 times removed

The "removed" part is a count of the generations between you, three, in this instance.

Good answer from Maxi and it wouldn't make any difference it the cousin is male or female.

First cousin, four times removed
