drogo
born:
died: 1051
father: tancred d'hauteville [1]
william and drogo seem to have probably really been brothers. they were present in italy by 1035 at the latest. drogo became count of apulia upon william's death and successfully repelled the byzantine invasions. also lord of venosa. he appears to have been murdered by the byzantines, but humphrey is also a suspect.
it is said that drogo appointed both humphrey and robert guiscard as counts.
