Here is a new site of 1850's Passenger lists on-line . http://www.maritimeheritage.org/ Read about this great new project and then click on the passenger lists. The Nicaragua route was made popular by Cornelius Vanderbilt, who developed the route in competition with the Pacific Mail Line, which had joined the Atlantic and Pacific Oceans via the overland Panama route. Vanderbilt's route was easier in that passengers covered most of the journey between the oceans by small boats and steamers across Lake Nicaragua. Passengers travelled by mule only a dozen miles to reach the Pacific Ocean. The following ships brought passengers to San Francisco during the 1850s. The lists will be added as time permits. ==== Ok, now you'll have to go the site to see what ships lists are posted and the ships that will soon be added! Hope you find your folks there! Have fun, Carolyn
