BIOGRAPHY
Welf was the son of the 9th century Frankish count Ruthardus of Metz. He is the earliest known ruler of the Elder House of Welf, a dynasty of European rulers from the 9th to the 11th centuries until 1055. The House of Welf consisted of two groups, one Burgundian and the other Swabian, of which the older is the Burgundian group. It is disputed whether the two groups formed one dynasty or whether they shared the same name by coincidence only.

Welf is mentioned only once, on the occasion of the wedding of his daughter Judith with Emperor Louis 'the Pious' in 819. Welf married Eigilwich/Heilwig, duchess of Bavaria, daughter of the Saxon count Isenbart. They had a son Konrad and two daughters Judith and Emma/Hemma who would have progeny, and a son Rudolf. Konrad and Rudolf accompanied their sister to the court of her husband, Emperor Louis 'the Pious'. Welf died in 825. About 826 his widow Heilwig became Abbess of Chelles near Paris.
