Halle Suggs was Sethe's husband in the Nobel Prize winning novel Beloved, by Toni Morrison. While Halle's name likely doesn't have the same origins as this entry, I suspect it's closer than the first entry for Halle.
People would immediately think the girl was named after Halle Berry. When she has been forgotten about, people will pronounce this name like 'hall' for sure. Also, ''Hallelujah!'' comes to mind from the spelling.
Halle may also be used as a variant of Hallie. It was in use for a while now, judging by censuses, albeit not commonly until Halle Berry became popular. I like Halle Berry, and the name is quite pretty.
I absolutely love this name! I love it. It sounds so pretty, but independent, and it works so well do speak. I do think it could be pronounced wrong (Hah-lee, not Hay-lee!), but I love it! One of the main characters in the book I am writing is named this.
