The Relationship Between Ben and Hedwig

Hedwig: "I have no linguist friends in a new country. I did try to present this and they were all very patient listening to me" Ben: "You can never ever worry if you feel like you need to be grounded." Hedwig: "Talk to Ben about food and I will drag you back to earth so quickly" And now it's time to play related or not - guess whether two words are etymologically related, or just coincidental.
