Frederick II, Holy Roman Emperor and his mistress Richina (Ruthina) of
Beilstein-Wolfsöden. Married Thomas of Aquino, count of Acerra.
Thomas of Aquino. Originally from Lombardy, the family made its first historical
appearance in 887. Since the end of the tenth century they had owned the castle of
Roccasecca. An earlier branch of the family held the county of Aquino until 1137; it
was that branch of that Thomas got his surname, not from the town of Aquino,
which was not his birthplace. Another branch later inherited the county of Acerra,
whose titleholder in 1221 was the first Thomas Aquinas; he possessed a viceroy´s
power over the southern part of the Italian peninsula. A follower of Emperor
Frederick II since 1210, he was named by the latter “judge” of the “Tillage Land”
(Terra di Lavoro) , his region in 1220, and that role he was under the jurisdiction
of the count of Acerra.
Selvaggia (1223–1244), married Ezzelino III da Romano
It believes that Selvaggia was born in 1221/1223 and died in 1244 in
Verona, where in 1238 he married Ezzelino III da Romano, was the
daughter of a woman belonging supposedly to the family Lancia.
Ezzelino III da Romano (April 25, 1194 – October 7, 1259)
was an Italian feudal lord in the March of Treviso (the
modern Veneto) who was a close ally of the emperor
Frederick II and ruled Verona, Vicenza and Padua for almost
two decades. He became infamous as a cruel tyrant though
much of his sinister reputation may be due to the propaganda
of his many enemies.
Ezzelino was son of Ezzelino II da Romano, ruler of Bassano,
and Adelaide degli Alberti di Mangona, who came from a
family of counts in Tuscany. At the age of four years he was sent as a hostage to
Verona. Nothing else is known about his childhood or education. In 1213 he took
part in the siege of the castle of Este, which belonged to his father's archenemy,
marquis Azzo VI of Este, who died in 1212, and later to his son Aldobrandino.
According to the chronicler Rolandino of Padua, the young Ezzelino already
showed a keen interest in siegecraft and acquired a hatred of the Este which would
last his entire life.
In 1249, after Selvaggia's death, he married Beatrice di Buontraverso.
In 1254, four years after Frederick II's death, he was excommunicated by Pope
Innocent IV, who also launched a crusade against him. He reconciled with his
brother and allied with other seignors of the Veneto and Lombardy, attacking
