The photos below are of all the nuns who were at Mercy during our four years. (They may have been at Mercy for more years than noted, we've listed only the years we attended.) We've also listed the subjects they taught during that time, which may have varied from year to year. Though most have passed, there are a number who are still active and whom we intend to invite to share in our reunion. We have noted their status as deceased, active or in assisted living, beneath their pictures. We thank Sister Madeline Moore (Stanislaus) for taking the time to provide all the updates, contact information and dates of death. We have included contact information for the sisters who are still active, in the event that any members of our class would like to contact them.

From the Sisters of Mercy website:
Sister Dorothy, affectionately known as Dot, lived a life of dedication to her God. She entered the Sisters of Mercy at the age of 19 in Syosset, New York, after attending Our Lady of Mercy Academy High School also in Syosset. She earned a bachelor’s degree in education from St. John’s University in Brooklyn, New York, and a master’s degree in education from Marywood College in Scranton, Pennsylvania.
When her sister died leaving young children. Dot took on the role of ‘mother’ until their young lives could be settled. Her many years of service in the field of education began at St. Therese of Lisieux in Brooklyn, New York, where she taught both in the 1940s and ‘60s and where she eventually served as principal for 12 years. Other schools that benefitted from her educational wisdom were St. Agatha, St. Brigid, and Catherine McAuley High School, all in Brooklyn, and St. Patrick’s in Bay Shore, New York, and Mercy High School in Riverhead, New York.
After her retirement, Dot lived at the Convent of Mercy, Brooklyn, and later moved to Marian Woods in Hartsdale, New York, where she formed new relationships with sisters from the several communities that lived there.
Her final days were spent at Maria Regina Residence in Brentwood, New York, where she was fully resigned to the frailties of her 97 years. Her motto was “My heart is restless until it rests in you.” She peacefully went into the arms of Jesus to quell her “restless heart,” finally resting in him.
