Ancestry adds Jamaica Civil Birth? Registrations

It's cold enough outside here that a virtual genealogical trip to the Caribbean is a welcome diversion.

Courtesy of Ancestry, and the company cooperative agreement with FamilySearch, comes a database titled Jamaica, Civil Birth Registration, 1878-1930 with 4,553,171 records.

It's a lucky dip. As there are no original images online recourse to the images in the FHL microfilm reference will be essential.
