Mary Hillyer Seaverns, daughter of Mr. and Mrs. Appleton H. Seaverns of Suffield, Conn., became the bride last Saturday of Robert Jean Saner II, son of Mr. and Mrs. Robert J. Saner of Springfield, Ill.

The Reverend William Atkinson, rector of St. Martin's Chapel (Episcopal) of Fairlee, Vt., performed the ceremony in the Colonial Room of the Horace Bushnell Memorial Hall in Hartford. The former Miss Seaverns is the great-great granddaughter of Reverend Horace Bushnell, an American Congregational minister whose works helped shape modern religious thought.

The bride, who wore an ivory satin and lace gown with a lace mantilla and carried a bouquet of white orchids, was attended by Mrs. David M. Hilyard, the bride's sister, as matron of honor. Bridesmaids were the Misses Judith Saner of Springfield, Ill, sister of the bridegroom, Mary Fox of Suffield, Conn., and Margaret Gill of West Harford. The groom served by G. Joseph Nicoud Jr. of Springfield, Ill. as best man. Ushers were Charles B. Seaverns of Beverly Hills, Calif., brother of the bride, David M. Hilyard of Suffield and William E. Cress of Boston.

Mrs. Saner is currently employed at George Washington University. Her father, headmaster emeritus of Suffield Academy, is president of the Horace Bushnell Hall in Hartford. Mr. Saner is a partner in the law firm of White, Fine and Verville of Washington, D.C. His father is the retired president of the Marine Bank in Springfield, Ill. The Saners will reside in this city.
