It’s been mentioned several times to focus on those records you can’t find in your homeland. The following is a good example of what to look for. A fellow genealogist had been hunting for a particular ancestor for twenty-eight years. All he knew about the person is that he might have worked aboard ships as a young man. Prior to his trip, he became aware of a Mariner Library in that ancestor’s country. While at the library, he found a letter written in the hand of the ancestor in what was known as the Marine Board correspondence. He also found meal lists from the 1850s and myriad other documents that related to his family. This is the type of information you won’t find in microfilm or online. It takes visiting the ancestral lands to accomplish such research.
