 Later he again approached the king and in 1088 attended the "Hoftag" diet in Quedlinburg, where the Brunonid margrave Egbert II of Meissen was deposed.The exact year of Thimo's death is unclear; since his son Conrad was born in approximately 1098, Thimo cannot have died long before this year.Alternatively, some researchers assume that Thimo was in fact Conrad's grandfather, and that Conrad's father was an unknown son of Thimo's with the same name, making a death year of 1090/91 possible, as given in a chronicle.
