Greetings Erica...I just came across your question which you posted last month. I was wondering if you received a reply? If you didn't let me know and I would be glad to assist you. Connect with me...just a hint...when you state permanent...do you mean a settlement which is still inhabited today or one that lasted for 'let's say' 50 years?
