Below is a list of passenger ships who brought some O'Briens to America. These lists were collected from around the internet. There are literally thousands of ships passenger lists available. These lists are the only ships passenger lists found that contain O'Briens (and variations of O'Brien) who emigrated from Ireland. There are probably more passenger lists with O'Briens on them that I have not found yet. 

To save space on the server, I have listed only those passengers named O'Brien (and variations). For a complete list, click on the ships name.  You will be transported to the original site that carries the complete passenger list.  If you know of any other ships, please let me know so I can add them to the list below.

Below are ships sailing from Ireland and England to the East Coast of America..
