The Garnier family came from Vitry, Champagne. Isaac Garnier (1631-1712) was born there and went on to study medicine and chemistry. However, because he was a protestant he was denied his apothecary’s diploma. In 1685 he fled to England where he became Apothecary General to Chelsea Hospital. His eldest son, also Isaac (1671-1736) followed in his father’s footsteps and became Apothecary General to the same Hospital in 1692.
Another member of the Garnier family settled in London. Daniel Garner was a goldsmith in London in around 1696. Other members of the Garnier family appear to have lived in Lisbon, Portugal. James, Samuel and Daniel were large woollen and cotton importers. They suffered under the Portuguese Government on account of not being English citizens. However, in 1718 they were able to prove that they had been naturalised in 1687 and were able to enjoy the same rights as English living in Portugal.
A Gedean Garnier came to England with his wife, Elizabeth, and their four children (Gedeon, Jean, Elizabeth and Isabelle). They appear in the records of the Huguenot Church of London on 12th June 1698. This branch of the Garnier family sought pardon for having reneged on their Protestant religion and attending Catholic Mass. They lived in the parish of St Jean, Spitalfields.
