I have only heard it pronounced Juh-koh-bee
I pn it juh-co-bee. REALLY like this name, btw!
I know a 4 year old named Jacobi whose name is pronounced "Juh-CO-bee" so that's how I pron. it.
I would pronounce it YA-coe-bee because that's how I heard it once, but other suggestions definitely make more sense. :)
I know 100% that is is pronounced Juh-coe-bee. I know several people with this as their surname.
I've always thought it was pronounced Jack-oh-bee, but I've never met anyone named it or even heard it said.
