Hi, um, sorta wondering, where does Bailey originate from ?

-Sally

First of all, Welcome to Sitcoms Online Sally :)

Do you mean where is the character from or where does the name come from? :)

I'll just cover both bases.

The character is from Chicago, IL. I remember her mentioning that in at least one of the Christmas episodes.

The name "Bailey" is of Old English origin. I found this information here: Bailey (http://www.thinkbabynames.com/meaning/0/Bailey)

I hope I was able to answer your question.
