Eighteenth-century cockroach found in slave-trading ship ledger

Insect's journey probably began in west Africa on vessel that sailed from La Rochelle in 1743 to Guinea

An 18th-century cockroach named Peri, discovered in the ledger of a French slave-trading vessel, has become a surprise addition to the National Archives after the book was opened for the first time in more than two centuries.

The insect's journey began onboard the slave-trading vessel that sailed from La Rochelle in 1743 for the Guinea coast. The crew later boarded a different vessel in modern-day Haiti bound for France, taking the ledger with them. But that ship was seized by British privateers during the war of the Austrian succession and sent into Plymouth.
