In 1864, Mother Cornelia Connelly, the foundress of the order, was informed that in Darby, Pennsylvania, an estate called Sharon, home of the Jackson Female Academy, was for sale and that it would be a suitable location for a convent and a school.

Mother Connelly promptly purchased the property, and soon after, a group consisting of six Sisters set out from Philadelphia to Darby to staff the order's newest school.

Also in 1890 a four-story, red brick school building was built to replace the existing structure that had housed the Jackson Female Academy.

By the late 1970s, the Sisters had been relocated to a mansion on nearby Woodland Avenue as well as to a Tudor-style house called the Cornelian House located on nearby School Street across from Holy Spirit School, which was also staffed by the Sisters.

The red brick school building and the chapel were left to languish and soon fell prey to vandals.

The junior high still stands today, but it was decommissioned in the early 1980s, and the students were transferred to Ashland Middle School in Glenolden.

Because of a lack of religious personnel, the school eventually fell under the administration of a lay faculty and closed its doors in 2003.
