This is a famous Huguenot (French) heraldic name, whose original holders originated from the Lanquedoc region. In many cases the spelling has been "anglicized" from Du Puy to Dupuy, Duppuy, Dupey, Dupoy, Dopois, Dupuis, Depois etc., but all have the same background. It is recorded that amongst the many "Du Puy" who fled after the revocation of the Edict of Nantes in 1685, were three brothers, Samuel, David and Philip Du Puy, and they all entered the Army of William of Orange in 1689, and took part in the defeat of James 11 at the Battle of the Boyne (Ireland) in 1690. Sad to relate David and Phlip were both killed, although Samuel later rose to high rank under the Duke of Marlboroguh. The recordings include Catherine Dupuy (1656), Dorothy Dupee (1684), Elizabeth Dupuis (1760) and James Dupoy of St. Mary-le-Bone, London in 1792. The first recorded spelling of the family name is shown to be that of Andrieu Dupuie, which was dated May 12th 1622, a witness at Threadneedle Street, French Huguenot church, London, during the reign of King James 1 of England and V1 of Scotland, 1603 - 1625. Surnames became necessary when governments introduced personal taxation. In England this was known as Poll Tax. Throughout the centuries, surnames in every country have continued to "develop" often leading to astonishing variants of the original spelling.
