Up until the early 1970s there’s a good chance someone in the family travelling to Canada transited through the port of Liverpool. I did. Knowing the ship, you don’t forget the name of the ship, and approximate date, you may only remember it approximately, records of the movement of ships in and out of the port in local newspapers will likely add detail about the journey.
The major Liverpool newspapers available through the British Newspaper Archive, and on Findmypast, are
|Liverpool Echo||35887||1879 – 1999|
|Liverpool Journal of Commerce||21610||1861-1862, 1864-1867, 1869-1887, 1889-1892, 1894, 1896-1897, 1899-1940|
|Liverpool Daily Post||17262||1855-1873, 1875-1877, 1881-1883, 1885-1890, 1892, 1894-1897, 1899-1920, 1939-1945|
|Liverpool Mercury||15294||1811-1835, 1837-1871, 1873-1897, 1899-1900|
The Post and Mercury are also digitized on newspapers.com. Check both, I found the OCR of one was different from the other.
From 1958 there’s a regular column Merseyside Shipping in the Liverpool Echo listing the name of the ship, whether it left or leaves (L), arrived (A), due (D), called (C), berthed (B), for (F), passed (P) or sailed (S), the port and the date. I found L and D entries for the ship I sailed on along with an article about a local Liverpool person, a widow leaving for Ontario to live with her daughter. It mentioned there were 1,000 passengers. From memory, it didn’t seem like that many.
Liverpool newspapers are good sources for maritime news in general; the Liverpool Journal of Commerce is especially strong.
