[2] Her father Walbert IV was related to the Frankish royal house, and her mother was Saint Bertilia.

They had four children, two sons and two daughters, all of whom are counted among the saints: Landericus, Madelberta, Aldetrudis and Dentelin.

Waldetrudis retired to Mons, while Madelgarius moved to his monastery in Hautmont, where he became a Benedictine monk and took the name Vincent.

Hoping to find greater seclusion, he moved around 670 with a few other monks to the second monastery, Soignies, where he became abbot.

Historian John Lanigan said Mauger was a distinguished Irish soldier in the service of Dagobert I.

It is an example of the not uncommon medieval practice of borrowing from the biographies of other saints when writing about one of whom there was insufficient information.

[7] He became the main patron saint of the town of Soignies, where there is a magnificent Romanesque basilica that bears his name.

His cult remains strong today and is celebrated at two major processions in Soignies each year, one on the day of his death, July 14, and the other on the Monday after Whitsunday.
