Early life :
Armand was presumably born sometime in the late 10th or 11th century in France. he came to Britain along with the Norman invasion, and was presumably gained the friendship of William the Conqueror sometime around this time.
Life in Britain :
Sometime after William I was made King of England in 1066, Armand provided various services to the king. Through the exact details of these services are unknown, they were believed to be shady and magical in nature. In exchange for these services, King William granted Armand a prime piece of land in Wiltshire, seizing the property from the former landholders.
This piece of property would go on to become Malfoy Manor, and would be the home of the Malfoy family for the next ten centuries. Later members of the family would expand the estate even further by annexing more property from the surrounding Muggles.
Behind the scenes :
- Armand may have attended Beauxbatons Academy of Magic and was sorted into Ombrelune, if the school already existed in his youth.
- Armand is a French name, derived from the Germanic name Herman meaning "army man".
- Malfoy comes from the French mal foi, meaning "bad faith".
- Therefore, the name Armand Malfoy could be taken to mean "army man of bad faith," which could describe any (or rather, almost any) of Malfoy's descendants.
