Scottish Emigration Database
If you’re trying to trace your ancestors from Scotland, the Scottish Emigration Database is worth a look.
The Scottish Emigration Database currently contains the records of over 21,000 passengers who embarked at Glasgow and Greenock for non-European ports between 1 January and 30 April 1923, and at other Scottish ports between 1890 and 1960.
