[2] He was a grandson of Boniface II, and was concerned with the troubles of Lombardy, at a time when so many princes were contending for the wreckage of the Carolingian Empire.

Before his father died in 884 or 886, he is accredited the title of "count".

He inherited from his father the titles of Count and Duke of Lucca and Margrave of Tuscany.

Between 895 and 898, he married Bertha (c.863–8 March 925), the daughter of Lothair II of Lotharingia, and widow of Count Theobald of Arles.

His widow Bertha was regent for their young son Guy.
