Hello,
I have just found notice of a Jamaican landowner (no doubt slave-owner) called Thomas Roper,Esq., whose 2 "reputed" sons disputed his property. The sons were called Thomas "the younger" and Joshua. Maybe you are familiar with http://www.afrigeneas.com/library/jamaica/acts.html.

I have just added an Ann Roper, "quadroon," to my family tree. She had a daughter with William Jonas, called Mary Evans Jonas, who was considered an "octoroon."
