The partition of the Diocese of Western New York was finally approved by the national church's 1931 General Convention.

In 1816 when John Henry Hobart, Third Bishop of New York, began his work, congregations were active in Avon, Canandaigua, Geneva, Clifton Springs, Catharine, and Bath.

The Woman's Auxiliary, working on both congregational and diocesan levels, helped raise money and direct the mission of the church under Bishops Reinheimer, Dudley S. Stark (1950-1962), and George W. Barrett (1963-1969).

The system's original purpose was to give voices to people and congregations throughout the diocese in using the Strong Fund.

[1] On February 24, 2024, the Very Reverend Kara Wagner Sherer, rector of St. John's Episcopal Church and current Dean of Chicago North Deanery, became the bishop elect of the diocese of Rochester.

Co-Consecrators of the service were Jack M. McKelvey, George Councell, John Croneberger, Mark M. Beckwith, Carol Gallagher, and Marie Jerge, Bishop of the Upstate New York Synod of the Evangelical Lutheran Church in America.

[5] The fifth Bishop of Rochester, Robert Rae Spears, Jr. (1970-1984), helped the diocese to deal with issues that rocked the church: how to interpret the Bible, whether to ordain women and gay people, and - among others - how to distribute the enormous legacy left to the diocese by Margaret Woodbury Strong's will.
