Book excerpt: Ever wanted to understand more about your ancestor's sea travels? What was life like aboard ship for both passengers and crew, how long did the journey take, what kind of conditions could be expected and what exotic locations might they have visited along the way? Following the tried and tested routes established by cargo ships, Karen Foy describes the development of passenger travel, the changing face of the vessels used and the demand for both comfort and speed. From transportation to trade, adventure to emigration, through persecution or for pleasure, she explains the reasons behind our ancestor's desire for overseas travel and reveals the records and archives we can search to complete our own genealogical journey.
