The other branches of the Ugoni, the old comital stock of the country between the Chiese, the Oglio and the Mincio, descended from the counts of Sabbioneta-Desenzano.
They straddle the Brescian and Mantuan borders: Mosio is a castle of the Brescian district, Marcaria lies in the Mantovano. In 1197-1203 Mantua often chose its consuls or podestà from these rural counts.

Overlord
Citizens of Mantua and of Brescia, by branch.
What it holds
- Mosio castle on the Oglio (in today's comune of Acquanegra sul Chiese), Brescian district, fief of the counts of Mosio (Brescia acquired two thirds only after 1226)
- Marcaria on the Oglio [medium]
- Redondesco [low]
- San Martino (Gusnago or dall'Argine) [not pinned]
How it was acquired
Ugoni inheritance (1107 list: Asola, Mosio, Marcaria, Montichiari, Calcinato, Lonato).
Allies and rivals
The commune of Mantua, whose offices they hold; their kin at Montichiari and Casaloldo; Verona (the Nogarole fight of 1201).
How things stand that morning
Rural lords with seats on the Oglio, citizens and officers of Mantua and Brescia; on 1 January 1200 none of them is known to hold Mantua's chief office (the 1199 podestà was Stefano da Torbiago).
Wealth
Lands and river rights on the Oglio [not pinned].
Military
Castles at Mosio and Marcaria [Marcaria's castle in 1200 not pinned].
Threats
- Brescia's and Mantua's appetite for their castles
- Verona
What the year holds
What happened next, if nothing in play changes it. Each event carries what it depends on and what would stop it.

Where the sources disagree
- The it.wikipedia list of Mantua's podestà calls the 1201-1203 family 'di San Martino' and gives a 'Corrado di San Martino' for 1203, where the Ugoni-Longhi article gives consuls Alberto of Casaloldo and Azzo of Mosio for 1203.
Evidence: Offices from it.wikipedia (Ugoni-Longhi, Podestà di Mantova, Mosio); seats and their bounds are thin.
On the map: Each seat is drawn as its modern comune; Mosio's part lies on Brescian ground although the record's realm is Mantua.
