Matilda's parents, Boniface and Beatrice of Lorraine first met on the occasion of the wedding of Conrad II's son Henry with Gunhilda of Denmark in 1036 at the city of Nijmegen shortly after Boniface had become a widower early that year. Beatrice was the niece and foster daughter of Empress Gisela of Swabia. A marriage covenant was arranged and one year later, in June 1037, Boniface and Beatrice celebrated their marriage in high style, keeping court at Marengo for three months afterward. According to the marital agreements, Beatrice brought important assets in Lorraine: the Château of Briey, the Lordships of Stenay, Mouzay, Juvigny, Longlier, and Orval that constituted the northern part of her paternal family's ancestral lands. Beatrice and her sister, Sophia, were the daughters of Duke Frederick II of Upper Lorraine and Matilda of Swabia. After the deaths of their parents she and her sister had been raised in the imperial court by their maternal aunt, Empress Gisela. For Boniface, the marriage to Beatrice, a close relative of the emperor, brought him not only prestige, but also the prospect to have an heir. His first wife had been Richilda, a daughter of Giselbert II, Count Palatine of Bergamo and their only child was a daughter who was born and died in 1014. Boniface and Beatrice had three children, Beatrice (named after her mother), Frederick (named after his maternal grandfather), and Matilda (named after her maternal grandmother). Matilda, probably born around 1046, was the youngest child.
