Livshin was one of the more interesting passengers on board the
Titanic with a few unexplained facts about his passage. He was a Jewish man of Latvian-Russian descent and was living and working as a watchmaker in Manchester, England when he decided to emigrate to Canada. He boarded the
Titanic in Southampton as a Third Class passenger with Montreal as his destination, leaving behind his pregnant young wife to whom he intended to send for once he settled in Canada. For some reason unknown to anyone, he was travelling under the name of Abraham Harmer, a name completely unknown to his wife or anyone else in his circles.
Very little is known about his activity on board the
Titanic and he must have jumped into the water quite late in the sinking.
Not sure what made you think that Seumas, but I'd be grateful to know the source. Here on his ET bio, it was speculated that he was picked-up from the sea by Lifeboat #14, which later rescued the ragged survivors from Collapsible A of course. But I have not seen any mention that Livshin/Harmer himself was on #A at any time. The only reference about him that I have found so far is in
George Behe's
On Board RMS Titanic: Memories from a Maiden Voyage, in which he is mentioned (as Harmer) as one of the men picked-up from the sea in Caroline Bonnell's account. The same account says that he was one of the 4 men who died on board the
Carpathia, the others being William Hoyt (picked-up by Lifeboat #14), AB William Lyons and Steward Sidney Siebert (both picked up by Lifeboat #4).
One of the references quoted for Livshin/Harmer on ET is Peter-Boyd Smith's book
Titanic: From Rare Historical Reports, a book that I have in India and should be able to check out in 3 weeks. If anyone knows of other sources, I request them to share them with us please.
