Don - you have just performed a great service, so glad you butted in! I have been trying to tell people that names, for people and places, change over time for 20 years now. There just is no single "correct" spelling, at least not until around 100 years ago in most places. You've done that very well with your chronology! I've printed it out to show to the doubters.
