Mr. and Mrs. Tulis had two sons, Jamie and an unnamed child. Both died as infants from a blood disease. The pair had a third son, Tobias.
From Blood and Ash
Mr. and Mrs. Tulis requested that their son Tobias not be considered for the Rite when he came of age as Mrs. Tulis could no longer have anymore children. Duke Teerman and Duchess Tereman denied the request. Mr. and Mrs. Tulis then fled Masadonia and hid in New Haven.
A Kingdom of Flesh and Fire
After Casteel Da'Neer and Poppy arrived in New Haven, Mr. Tulis was killed as punishment for attempting to kill Poppy. Afterwards, Cas went to explain to Mrs. Tulis about her husband's death, but she did not believe that her husband would participate in the attempted murder of Poppy. Cas presented Mrs. Tulis with the options of staying with the people in New Haven or safe passage to another town.
Mrs. Tulis chose to run away with her son Tobias. While walking through the snow, Mrs. Tulis happened upon Lord Chaney and the Ascended. She told Lord Chaney that the Dark One had killed her husband and that the Maiden was at New Haven. When Lord Chaney confronted Elijah about whether or not the Maiden was at New Haven, Elijah denied it. Lord Chaney brought out Mrs. Tulis and snapped her neck.
Although Lord Chaney informed Poppy that the Ascended took Tobias to the Keep, it was heavily implied that the child was killed.
Poppy thinks of Mrs. Tulis as she kills Lord Chaney. Poppy later carves Mrs. Tulis's name on the wall of those killed by the Ascended.
Mrs. Tulis loved her family. She felt defeated because two of her sons had died, the third was destined for the Rite, and she could no longer have children.
Mrs. Tulis was described as fair-headed.
