It is possible to trace Caribbean ancestors as far back as the mid-1800s without going outside of the UK.
It is likely that you will touch on the period of slavery during your Caribbean family history search.
During the 1700s there were people from the African continent and the Caribbean working as domestic slaves in the homes of the rich across the UK. The practice was made illegal in 1774.
The Slave Trade began in the mid 17th Century and included the forced enslavement and transportation of Africans to the Caribbean. They would be sold to landowners, becoming their property and made to work on plantations and carry out domestic work. They were frequently split from their families and moved to other countries.
The Slave Trade ended in 1807. Slavery ended in the British Empire with the passing of the Slavery Act in 1833. However, many enslaved people were still apprenticed to their masters for 4 years, so would not have been freed until 1838.
