And nothing on Jamaican Family Search (nothing to do with FamilySearch).
But FamilySearch has the baptism of a Robert Wason, 26 Aug 1797 Kingston, Jamaica, parents George Wason and Ann Roberts, with an image of the PR entry:
https://www.familysearch.org/ark:/61...3A1%3AVH6H-NHP
Image number 29. Date of birth shown as June 9th 1797, and Ann Roberts is described as "a mulatto woman".
Edit - this record does also come up on Ancestry, but I would have had to put George Wason in as father's name on my search.
