 Berthe et son Abbaye de Blangy", Lille, 1892).Two buildings which Bertha constructed had fallen down, but an angel in a vision guided her to another spot, and there after many difficulties a nunnery was built, which she entered with her two eldest daughters, Deotila and Gertrude.A still later legend represents Gertrude as much persecuted by the attentions of a great noble, Roger, who wished to marry her by force, but she was saved from his violence by her mother's firm courage and trust in God.
