One of my many interests is genealogy, I have traced my family and my husband's family back to their arrival in America. Below are some great sites that I have used over the years in my research. All of the sites I have listed are free with no fee to use them. If you find a piece of your family history or something interesting leave me a comment! I love history and would like to hear if this article was helpful to my readers.
Immigrant Ship Transcribers Guild - this amazing site has the transcription of passenger lists that arrived in America for thousands of ships! The listings start in the 1600's and go through the 1950's. http://www.immigrantships.net/
