When the Pilgrims fled religious persecution in England, they settled in Leiden. They lived and worked in Leiden, and some married there or had children baptized there. They left for America on the Mayflower in 1620, but not after leaving traces in Dutch records.
The Leiden Archives has transcribed several of these records. They used to be available on a separate website, which has been offline for several years. The transcriptions and English abstracts of these records have now been made available on this website.
