Mary Catherine Chase

Mary Catherine Chase (pen names, F. M. Edselas and Winnie Rover; 1835-?) was a 19th-century American Catholic nun and writer. A fervent Episcopalian for years, she was later influenced by a Catholic woman and entered an enclosed order. Starting in 1874, she wrote under the pen name "Winnie Rover", switching to "F. M. Edselas" in 1892.

Mary Catherine Chase was born in Pepperell, Massachusetts, July 1, 1835. She lost her mother as an infant, and was raised by two maternal aunts. She was home-schooled, and later, was educated in the schools of Springfield, Massachusetts at Mount Holyoke College, and at the State Normal School of Westfield, Massachusetts, from which she was graduated in 1855. At the age of 19, and under the spiritual guidance of Rev. Alexander Hamilton Vinton, D. D. she was confirmed in St. Paul's Church, Boston, and remained for years a fervent Episcopalian.

Having chosen the vocation of a teacher, she drifted to the west. There she met a Catholic woman who influenced her. After entering an enclosed order, Chase took a religious name, but she also felt urged to contribute to literature for young Catholics, and using the pen name of "Winnie Rover", she published books of travel for children, the "Neptune Series", as well as several dramas, and various manuals for the classroom, notably Practical Science.

Since 1892, using the pen name of "F. M. Edselas", she wrote upon subjects of public interest, giving the general impression that the writer was a man with, "How to Solve a Great Problem," "Institute of Woman's Professions," "Educational Bureau and Journal," etc. The appearance of these articles in a leading Catholic periodical and the favorable comment they received, resulted in her choice as one of the contributors to the Columbian Catholic Congress. Her paper was upon "Woman's Work in Religious Communities." Later, she gained new admirers in the literary world with, "A Visit to Ramona's Home," "In a City of the Clouds," "Constantine Zrumidl," and "What Shall We Do With Our Girls?".
