In When We Were Strangers, Irma crosses the Atlantic on the Servia. This was a real ship that received heavy use in transporting emigrants. I liked the name, but took the liberty of having the ship leave out of Naples rather than her standard port of Liverpool. You can read about the Servia’s long history and see photographs and drawings here. I discovered this site after writing the novel; much of my description of ship conditions during Irma’s voyage comes from Philip Taylor’s classic study: The distant magnet: European emigration to the USA.Passenger lists from various European cities can be found through the Immigrant Ships Transcribers Guild.
