Hi It doesn't appear that the Laurentic is in the Ellis Island database for that time.The website "Searching for Ships in the Ellis Island Microfilms in One Step" Click Here will list the arrivals. Search on Laurentic (not RMS) It could be that it went to another US port or Canada. You would have to get the microfilm records for that Carla
I have a signed letter by 'The Ladies & Gentleman & Saloon passengers on the S S Laurentic dated April 27th 1912. It is to my Great Great Grandfather Captain John Mathias R.N.R They sailed from Portland Me., to Liverpool England
