Bryannah is a modern American elaboration of the name Brianna, which is the feminine form of the Irish name Brian. It is derived from the Old Celtic element 'bre' meaning hill, or by extension, high and noble. The 'h' ending is a stylistic addition common in contemporary American naming to add a softer or more unique visual flair.
