Been doing a little research and have found a book online about the fort and the migration of the people in 1850. There were 50,000 who passed thru there, Elizabeth Jobe Francis probably one of them. Chapter VII covers the 1850 time frame, but it is all interesting to read. http://www.nps.gov/fola/history/contents.htm I have even found on this same site a map showing the CA trail that Henry and elizabeth would have been on when he died. http://www.nps.gov/fola/history/images/map2.jpg This is a map showing the ruins that were still there in 1937. Some where there in 1850. http://www.nps.gov/fola/history/images/map3.jpg Freida
