There were 113 Irish in 3rd class, not counted as British, who numbered 120, but even added together, they were less than a third of the total 708. There were actually more Scandinavians than Irish--24 Norwegians, 104 Swedes, and 59 Finns. There were also a surprising number of Syrians, 79, and they had a significantly higher survival rate than the others.

Pity the poor Bulgarians, 33 passengers, but none survived. Check Demographics of Passengers .
