Rosier (male)

Rosier was one of the earliest members of the Death Eaters. He joined Lord Voldemort around 1955 and he possibly fought in the First Wizarding War. It is possible that he attended Hogwarts School of Witchcraft and Wizardry with Tom Riddle. He was most likely the father of Evan Rosier. It is possible that Rosier was deceased before the start of the Second Wizarding War. If not, he presumably fought in several battles, and was either killed or imprisoned after Voldemort's final defeat.

Early Life
Rosier might have attended Hogwarts at the same time with Tom Riddle, and he may have been a member of Slytherin house, as well as a member of Tom Riddle's gang and the Slug Club. After Hogwarts, Rosier became one of the earliest Death Eaters.

First Wizarding War
Rosier fought in the First Wizarding War along with many other Death Eaters. He was also one of the Death Eaters who travelled to Hogsmeade, "to say good luck to Voldemort, during his attemp to ask for work at Hogwarts, along with Nott, Mulciber and Dolohov. It is possible that he was the father of Evan Rosier, who attended Hogwarts with Severus Snape in the 1970s, and who was killed by Aurors in the end of the First Wizarding War. After Voldemort's first downfall, Rosier was presumably killed, imprisoned or defected. It is most likely that he was one of the Death Eaters who didn't search for Voldemort.

Second Wizarding War
It is unknown if Rosier was still alive during the Second Wizarding War; if he was, he possibly fought in several battles, including the Battle of Hogwarts.
