Looking for Hegger and Hager

Recently I've made a friend named Hager. Hegger and Hager are both German names, and she told me that "Hegger" was a warrior of sorts and "Hager" was a hedgeclipper... of sorts. That's about all I know. If anyone knows how far back these names go, maybe we could find out how we're related (if we indeed are). Unfortunately, I don't have any more details to give.
