Bernard was born in 797, the illegitimate son of King Pepin of Italy, himself the son of the Emperor Charlemagne. In 810, Pepin died from an illness contracted at the siege of Venice. Despite being illegitimate, his grandfather allowed Bernard to inherit Italy.[1] Bernard married a woman named Cunigunde, but the year of their marriage, and her origins are obscure. Some sources refer to her as "of Laon". They had one son, Pepin, Count of Vermandois, who was born in 817.
