The Maritime Heritage Project

World Harbors and International Migration from The Maritime Heritage Project.

Dear Maritime Heritage Visitors: This season The Project is asking visitors to help keep the site growing. While publications and prints to aid in your research are included (and bring in a few dollars per sale), the director is now "officially" asking if you will kindly donate. If everyone reading this right now gave $5, it would help provide additional names and stories to the more than 100,000 ship passengers arriving in San Francisco during the 1800s. This 18-year-old Project is free and is accessed from every country around the world. The Maritime Heritage Project (,, is basically a one-person operation developed and managed by the now 70-year-old great-great-grandaughter of Captain James H. Blethen, Master Mariner. Costs include equipment, research materials and time. The Maritime Heritage Project is special: it keeps alive our history of shipping, commerce and migration during an era when more people changed locations than in any other century in the history of the world. It is a resource where all can research ancestry and find heretofore "lost" family members at no charge. If you have visited our site and found it of value, kindly take one minute to keep it growing. Thank you very much. ~~ D. A. Blethen Levy
