For my wife and me, a visit to the restored immigrant settlement in Plymouth, Massachusetts, helped us to understand her family better. Her ancestors include a Mayflower passenger, John Howland, 1592 to 1673. An immigrant, again.
A guideline or two: think of items and places that can be seen, visited, and/or used, or even just tucked away in a drawer. Choose quality, durable mementos. For families of the 21st century, I suppose mementos in electronic media will be important. Can posts in your blog fill such a function? I hope that some of posts might.
