Saint Amalberga, also referred to as Amalberga of Maubeuge, was a Merovingian nun in the 7th century.
The biography of Amalberga of Maubeuge is probably written by Abbott Hugo of Lobbes (1033–1063) between 1033 and 1048. Apart from a few Merovingian details, her genealogy was copied from another 11th-century hagiography, namely the Martyr story of Catherine of Alexandria.
Saint Amalberga was born in Brabant. Her father was Saint Geremarus and is said to be the niece of Pippin of Landen. She married the Duke Witger of Lotharingia and bore 5 children. It is said that all her children became saints: Emebert, Reineldis, Pharaildis, Ermelindis and Gudula.
After the birth of Gudula, their youngest child, Witger decided to become a Benedictine in Lobbes. Saint Amalberga, on the other hand, joined the Benedictine nuns of Maubeuge.
Saint Amalberga’s feast day is celebrated on July 10 and should not be confused with another saint, virgin Amalberga of Temse who died in 772.
