Alphard Black

Alphard Black was a pure-blood wizard from the noble Black family and was a Slytherin student at Hogwarts School of Witchcraft and Wizardry.

Biography
Alphard was the middle child of Pollux Black and Irma Crabbe, and brother of Cygnus and Walburga. He was born sometime after his sister and before his brother and grew up in 12 Grimmauld Place.

Alphard passed away of unknown causes sometime in 1976 or 1977; he was aged between 38 and 52. In his will, he left a "decent amount of gold" to his nephew Sirius, who was seventeen at the time. He was posthumously disowned and removed from the Black family tree tapestry by his sister Walburga, and Sirius believed that this act of charity towards him was the reason.

Personality
Judging from Alphard's action, helping his nephew when he ran away from home, it can be deduced that he was, at the very least, capable of love and fondness; and he might have been kind and compassionate in his life, vastly different from his sister.
