That's amazing! My grandfather worked first as boot boy, then as an assistant steward on RMS Empress of Britain 1906-1907 which I guess was actually part of the Canadian Pacific Railway company rather than the White Star. Her sister ship was the Empress of Ireland which collided with a collier in the St Lawrence River in 1914 and sank; over 1000 lives were lost. But Grandfather was well off ships at that time although the voyaging family story shifts to both my grandmothers.
One grandmother immigrated to Canada from Ireland. I haven't been able to find definitely which voyage she arrived on as her name was fairly common, Mary Kate Reilly. But once she married my grandfather in 1910, she became Torrance and that was less common so I was able to find a record of her voyage to and from Ireland on the Pretorian, which was at first part of the Allan steamship line, in 1912 with my only a few months old mother. It amazes me to think that she traveled, alone, with an infant by choice back to Ireland to see her mother and to also pick up her youngest sister, whom she brought back to Canada with her. Ugh 1912, with a baby! That grandmother made one more voyage many years later, in 1957, on the Carinthia to once again visit her sisters who lived in England and then return to Canada. I remember seeing her off in Montreal and actually seeing her very small cabin--those were the days, when you could be on board as a visitor until they called "All ashore who's going ashore...."
My other grandmother came to Canada from Scotland to marry my grandfather in 1907; she traveled on the Ionian which was another ship that belonged to the Allan steamship line. Then in 1919, pregnant with my aunt and with my 8 year old father in tow, she decided she wanted to go "hame" to her mother in Dundee. They sailed on the Minnedosa, which belonged to the Canadian Pacific steamship lines. Dad said Grandma was so seasick (and probably morning sick too) that she stayed in the cabin the whole voyage and he was left to ramble around the ship, being well looked after by the sailors who showed him all the engines and how the machinery worked, which left him with a lifelong love of all heavy machinery. When they arrived in Liverpool, Dad said there were so many soldiers who were traveling back from France after WW1 had ended that Grandma became overwhelmed. He remembered a kind young soldier taking her by the arm at the dock and saying "Now, it's alright mum, you just sit here and have a cup of tea and I'll see that you get your tickets for the train to Scotland."
A year after arriving, Grandma had had enough of Scotland and decided to go back to Canada, just as my grandfather was getting ready to move back to Scotland, having saved up enough money. So back my dad and my grandmother traveled, this time with my months-old aunt, on the Sicilian, again an Allan line ship.
