In the 1831 Slave Registers, Bon Air appears as a sugar plantation the property of the heirs of Richard Allport, of which the said Francis Bickley is in possession as manager, previously the property of Francis Bickley. The connection between Francis Bickley and his attorneys and assignees Sophia Beata Gilson (a schoolmistress in Essex) (q.v.) and Martha Craston (untraced) is not yet known.
At least two men called Francis Bickley born in Trinidad - neither old enough to be the Francis Bickley of Bon Air but each possibly a son - appear in the British census, one born c. 1821 a surgeon/dentist lodging at 1851 in Paternoster Row, Abbey Street Cumberland and one born c. 1833 a Private in the Life Guards living in barracks at Windsor in 1861.
Richard Allport was a Bristol merchant who died in Trinidad in July 1829. Again, his relationship with Sophia Gilson and Martha Craston is unknown.
