Ancestry.com is offering a free trial of its services, including a search of immigration and naturalization records.  You can read more about it here.

Ancestry.com, the world's largest online family history resource, today announced an entire week of free access to its popular U.S. and International Immigration and Naturalization records. The free access week begins August 29^th and runs through the Labor Day holiday ending September 5^th. During this time, all visitors to Ancestry.com will be able to search for free the indices and images of new and updated U.S. immigration records as well as selected international immigration records from the United Kingdom, Ireland, Italy, Australia, Canada, Germany, Sweden and Mexico. Millions of Americans can trace their family history to other countries, and these collections provide valuable information about the travels and journeys that brought them to America or other countries around the world.

While I realize we are all individuals who make our own choices in life and our ancestors actions have no bearing on our own, I think it's interesting to know the stories of past generations, and it could be important to know your family's medical history.  I've emailed both of my grandmothers to see if they have additional information to help me with my search.  If I find anything interesting, I'll be sure to post about it.
