DEASE, MARY TERESA, MOTHER

Missionary; b. Dublin, Ireland, May 7, 1820; d. Toronto, Canada, July 1, 1889. She was the eldest child of Oliver and Ann Dease and was baptized Ellen. In 1847, immediately after profession at the Irish motherhouse of the Institute of the Blessed Virgin Mary, Rathfarnham, she became a pioneer missionary to Toronto, Canada, new episcopal see of Bp. Michael Power, who died within a week of the sisters' arrival. The sisters were harassed by the severity of the climate, poverty, and insecurity; within two years, three of them died. In 1851, youthful Mother Mary Teresa, as superior, accepted responsibility for the first convent of her institute in America. She was superior general until death, at which time Loretto schools flourished in many cities of Ontario and in Illinois. A simple monument marks her grave in the gardens of Loretto Academy, Niagara Falls, Ontario.

Citation styles

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

Notes:
  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
