Saint Lucia,
1815.

The returns, most written in French by local registrars, record each enslaved man, woman and child by name, with age, birthplace, occupation, and family ties. This map presents a complete transcription of the plantation registers, arranged geographically across the island's thirteen historical quarters, including Dauphin and Praslin, quarters that no longer exist on the modern map.

Every circle is a plantation: its size reflects the number of people registered there, its colour the main crop. Because the registers record only the quarter, not exact coordinates, positions are indicative, not survey-accurate: a plantation pinned to a surviving place name sits on a solid ring, while the rest, arranged within their quarter, sit on a dashed one.

Who the owners were

"Owner" covers several very different people in this register. Some returns are signed by a planter living on the estate and running it themselves. Roughly a third are signed by women, most of them widows, recorded in the French of the period as veuve, who had inherited a plantation from a husband and continued to hold it in their own name. About one estate in ten names a separate resident manager, hired to run the property day to day for an owner who lived elsewhere, was elderly or unwell, or was a minor represented by a guardian. A number of returns are signed not by the owner at all but "by authority of" a relative, an attorney, or an administrator, the paper trail of an estate managed at a distance. At least one return in this register was signed on behalf of an owner recorded as a free woman of colour, a reminder that plantation ownership on Saint Lucia was not the exclusive preserve of white colonists; free people of colour were a recognised, property owning class across the French Caribbean, and some held land and enslaved people in their own name.

Most of these owners, or their parents or grandparents, had taken up land under French colonial rule, when Saint Lucia was granted and settled largely by planters from France and the French Antilles. The island changed hands between France and Britain fourteen times, with Britain's final conquest in 1803, and its cession was confirmed by treaty in 1814, a year before this register was compiled; through all of it, most estates simply continued under the same French speaking families. From there, ownership moved the way property usually does: passed down to children and widows, divided among heirs, married into other planter families, bought and sold between them, or, for owners who left the island altogether, run at a distance by a paid manager or attorney acting on their behalf.

Where the enslaved people came from, and how they arrived

Of the 12,726 people named in this register, about three in four were Creole, meaning born in the Caribbean rather than in Africa, and most of those were born on Saint Lucia itself. That balance reflects timing: Britain's Parliament had outlawed the transatlantic slave trade in 1807, so by the time this register was taken in 1815, an enslaved population that had grown mainly through birth on the island, not through new arrivals from Africa, had become typical across the British Caribbean.

The roughly one in five people recorded as African born had reached Saint Lucia earlier, carried across the Atlantic on slave ships as part of the same transatlantic trade that supplied the whole Caribbean, and the register itself preserves a trace of where: a clerk wrote down a region or a people, such as Igbo, Congo, Mandinka, or Gold Coast, alongside each African born person's name. Grouped into broader regions, the largest numbers in this register trace to the Bight of Biafra, the Senegambia and Upper Guinea coast, and West Central Africa around the Congo and Angola coasts, with smaller numbers from the Gold Coast, the Bight of Benin, and the African interior.

Not every Creole entry means born on Saint Lucia, either. A smaller number were born elsewhere in the Caribbean, chiefly Martinique, Grenada, and St. Vincent, and arrived on Saint Lucia by sale, inheritance, or transfer between estates, or travelling with an owner who relocated. That movement is a direct consequence of Saint Lucia's contested colonial history: as the island changed hands and estates changed owners, the people those owners claimed were treated as property that moved with them.

Names given, names kept, names lost

Each person in this register carries two names: a given name, usually a French Christian name such as Jean, Marie, or Fanchette, assigned at baptism, and a second name the register calls a surnom. Far more often than not, that surnom is not a family surname in the modern sense but a byname: descriptive, sometimes affectionate, sometimes cruel, and typically shared informally among siblings born on the same plantation rather than inherited down a family line the way a European surname would be. Almost nowhere in the register does an African born person's own name from before capture survive; what was recorded in its place, in nearly every case, was a French name given after arrival and a birthplace noted as a region rather than a home. Forced baptism and renaming at the point of sale were themselves part of how the system operated, and the effect on the written record is stark: for most of the African born people in this register, the birthplace field is the only trace of the name and identity they carried before enslavement.

That is also why the record trail for many families changes abruptly at emancipation. Full freedom arrived on 1 August 1838, and formerly enslaved people then needed a fixed, legally recognised surname for the civil registers, marriage records, and land documents of a free society, something the plantation system had never required of them. Some kept the surnom already recorded here, particularly where it had functioned for a generation or more as a shared name among brothers and sisters. Others took the name of a former owner or plantation, the name most consistently attached to them in official paperwork. Still others chose a new name outright, a deliberate break from an identity slavery had assigned rather than one they had chosen. All three patterns can be found among Saint Lucian families today, which is part of why a name search on this map can trace a line up to 1838 and then go quiet: emancipation is not only a legal turning point in this story, but very often a naming one.

This account draws on the register's own data (owner signatures, manager listings, and recorded birthplaces, as transcribed here) together with the general documentary history of Saint Lucia and the wider French and British Caribbean. Where a specific claim about an individual cannot be verified beyond the register itself, it is described as an attested pattern in this dataset rather than a fact established elsewhere.
