S/S HAVERFORD

S/S HAVERFORD MAY 18, 1906 SAILING FROM LIVERPOOL TO PHILADELPHIA My grandfather, Anshel Binembaum, claims that he sailed on the S/S Haverford that departed Liverpool, England on May 18, 1906. The ship supposedly arrived in Philadelphia, PA, USA on May 28, 1906. This is according to the Declaration of Intention papers that he subscribed and sworn to for his Naturalization. In doing a search on the S/S Haverford I got to URL /ships/have1/ The web page does not show any sailing for the year 1906. QUESTIONS: Was the S/S Haverford chartered to some other company during 1906? Can anyone advise me as to where I can find the passenger list for this sailing?
