I recently looked through a reprint of Ussher's Chronology and I am pretty sure he had the date 606 BC for the fall of Jerusalem. His work dated to about 1650.
As an aside, I was simply astounded at the monumental work he produced; it is really impressive for one guy in the 1600's. Many of the dates, etc have been proven incorrect, but it was an impressive work of scholarship for the time.
