Commentary Purg XIV 105

Ugolino d'Azzo was born in Tuscany, but at some point moved to Faenza (and thus, in Guido's words, 'lived among us').  He was the son of Azzo degli Ubaldini and thus related to both the cardinal Ottaviano degli Ubaldini ([Inf X 120]) and the archbishop Ruggieri degli Ubaldini ([Inf XXXIII 14]).  He was married to a daughter of Provenzan Salvani ([Purg XI 121]) and died at a ripe old age in 1293.
