Baby name help for a girl!?

Okay so my fiance and I just found out we are expecting! We pretty much had this name picked out for the past two years already--but we just want to hear some different options. If it's a boy, it's definitely going to be John Michael--after him. Even though I love the name Shawn--oh well. :) If it's a girl--we had pretty much decided on Jaelyn Donna. Can anyone think of any other unique, or older "J" names? I'm into unique and older names that are not used as much anymore. Thanks everyone!
