This Pitcairn Islands register book has been extracted from an original diary of events (of which there is a copy in the Society of Genealogist's Library). From this book, the 25 marriages that are noted, covering 1825-1854, have been extracted for this index. It's a wonderful genealogy tool for anyone with ancestry connected to the islands who is building a family tree or exploring their family history.
You might also find your ancestors in our extensive Census, Land & Survey Records
