made Marchese by Berenger II in 960
https://en.wikipedia.org/wiki/Oberto_I
Oberto I Obizzo (also Otbert) (died 15 October 975) was an Italian count palatine and 
margrave and the oldest known member of the Obertenghi family. He was, by heredity, 
Count of Milan from 951. Otbert's father was Margrave Adalbert, about whom nothing 
is known other than his name and title.

Soon after assuming the Italian throne, Berengar II reorganised his territories south of 
the Po River, dividing them into three new marches (frontier districts) named after their 
respective margraves: the marca Aleramica of Aleram of Montferrat, the marca 
Arduinica of Arduin Glaber, and the marca Obertenga of Oberto. This last division 
consisted of eastern Liguria and was also known as the marca Januensis or March of 
Genoa. It consisted of Tuscany with the cities of Genoa, Luni, Tortona, Parma, and 
Piacenza.

In 960, he had to take refuge in Germany. The next year, Pope John XII asked Otto I 
of Germany to intervene in Italy to protect him from Berengar. When Otto took control 
of Italy, Oberto was able to return to his lands, with the title of count palatine 
confirmed by Otto.

He was succeeded as Count of Milan by his sons Adalberto II of Milan and later 
Oberto II. His great-grandson Albert Azzo II, Margrave of Milan founded the House of 
Este; this makes Otbert the progenitor of the House of Este as well as its branches, 
the House of Welf and the House of Hanover.
