Hollis

Hollis is a boy's and girl's baby name of Old English origin, a habitational surname from the Old English holegn meaning "holly tree" — for someone who lived near a holly grove. Holly was considered a sacred tree in Celtic and later Christian tradition.

Hollis carries a pleasant, outdoorsy quality with its nature-origin root, while the -is ending gives it an appealing, slightly academic feel. With over 15,000 U.S. births recorded, it has been a steady name used for both boys and girls, though primarily masculine in historical records.
