Dominican sister taught in Omaha archdiocese

Sinsinawa Dominican Sister Margaret Ann “Peggy” Brennan worked hard to instill the Dominican values of truth, compassion, justice, community and partnership in her students during a 41-year teaching career that included service in the Omaha archdiocese.

Sister Peggy, whose religious name was Sister Eunice, died April 5 at St. Dominic Villa in Hazel Green, Wisconsin. She was 86.

A funeral Mass was held April 14 at her order’s motherhouse in Sinsinawa, Wisconsin, with burial in the motherhouse cemetery.

A native of Sioux City, Iowa, Sister Peggy entered religious life and professed first vows in 1958. She took final vows in 1961.

She began her teaching career at the former Holy Angels School in Omaha from 1960 to 1962. From 1962 to 1977, she also taught at schools in Bloomington, Illinois; Greenwich, Connecticut; Madison, Wisconsin; and Sioux Falls, South Dakota.

Sister Peggy served as secretary to the prioress of the Dominican Sisters of Sinsinawa from 1977 to 1986, before returning to teaching at Dominican High School in Whitefish Bay, Wisconsin, where she taught until 2010. She continued serving at the high school as a substitute teacher and library volunteer until 2018.

She is survived by nieces and nephews, and her fellow Dominican sisters.
