Took a quick glance back, and did not see mention of the book I thought had been posted, so here goes...
Freedmen of Barbados: Names and Notes for Genealogical and Family History Research
Compiled by Jerome S. Handler, Ronald Hughes, and Ernest M. Wiltshire, 1999, ISBN 0-9668919-0-2, Price $15.00, Published for the Friends of the Barbados Archives by the Virginia Foundation for the Humanities and Public Policy, Charlottesville, Virginia
This is a small paperback book, which consists of a list of names of folk who are clearly identified as "freedmen" in various primary historical sources, and gives the sources where they were found, and sometimes additional notes.
I ordered my copy directly from Professor Handler at the Virginia Foundation for the Humanities, 145 Ednam Drive, Charlottesville VA 22903-4629. It could also probably be ordered from the Barbados Archives.
