Kuka naimisissa Sibylla of Acerra?

Sibylla of Acerra (1153–1205) was Queen of Sicily as the wife of King Tancred. After Tancred's death, she was regent in 1194 for their son, King William III. She was the sister of Count Richard of Acerra.

Tancred (Italian: Tancredi; 1138 – 20 February 1194) was King of Sicily from 1189 to 1194. He was born in Lecce, an illegitimate son of Roger III, Duke of Apulia (the eldest son of King Roger II) by his mistress Emma, a daughter of Achard II, Count of Lecce. He inherited the title "Count of Lecce" from his grandfather and is consequently often referred to as Tancred of Lecce. Due to his short stature and unhandsome visage, he was mocked by his critics as "The Monkey King".
