He married Garsenda, daughter of
Ermengol of Albi, and probably had three children. His sons were
Raymond II, whom he associated in the countship by giving him
Rouergue (before 898), and
Ermengol, who inherited that same province. It has been suggested for onomastic reasons that Odo was the father of Garsenda, wife of
Wilfred II of Barcelona.[3]
