St. Bertha, Widow, Abbess
She was persecuted by Roger, or Rotgar, who endeavored to asperse her with King Thierri III., to revenge his being refused Gertrude in marriage. But this prince, convinced of the innocence of Bertha, then abbess over her nunnery, gave her a kind reception and took her under his protection. On her return to Blangy, Bertha finished her nunnery and caused three churches to be built, one in honor of St. Omer, another she called after St. Vaast, and the third in honor of St. Martin of Tours. And then, after establishing a regular observance in her community, she left St. Deotila abbess in her stead, and shut herself in a cell, to pass the remainder of her days in prayer. She died about the year 725. A great part of her relics are kept at Blangy.
