[17] The magazine's editors "had been forced to commandeer a whole wing of their floor in a downtown Chicago skyscraper just to answer letters and phone calls about Cayce".
[24] Bro's fiction for young people included Stub, A College Romance,[25] Three—and Domingo,[26] The Animal Friends of Peng-Yu,[27] and How the Mouse Deer Became King.
[33] Her first novel, Sarah, was praised in a review in the Chicago Tribune: "No longer can girls in their upper teens legitimately complain there aren't being written for them books mature enough to hold their interest and help them find the answers to living they all are seeking.
For this portrait of a talented young musician from her childhood to her early 20s is both intimate and moving, sparing none of the inner conflicts, her happiness and sorrows, her triumphs and defeats".
[38] A 1945 review of her book Every Day a Prayer in the Journal of the American Academy of Religion said: "The uniqueness of Margueritte Harmon Bro's anthology is the selection of passages not only from the Hebrew-Christian scriptures, but from Mohammedan, Persian, Chinese, and Indian religious literatures and in addition from a wide variety of individual authors, ancient and modern, religious and secular".
[39] On March 4, 1939, Bro's non-fiction about cities, titled Urban Scene, was recommended by the Indianapolis Times as a supplement to the book Church written by Chicago Theological Seminary associate professor Samuel C.
[40] A July 1939 review from The Baptist Herald stated: "For the Christian who is interested in this subject of the church and the city but who must 'read as he runs' because of limited time, no finer recommendation could be made than the paper-bound handbook, "Urban Scene" by Margueritte Harmon Bro".
[41] In September 1972, Bro's children's book Su-Mei's Golden Year was recommended for use in elementary schools by the Arkansas Department of Education in relation to learning about ethnic groups.
[42] Su-Mei's Golden Year was reviewed favorably by the New York Times: "The author's perceptive characterizations make these people as real as old friends.
[43] Her biography on the University of Nebraska Omaha Alumni Association's website states: "If nothing else, Margueritte Harmon Bro proved she had staying power.
One of the first students to attend Omaha University in the 1910s, Bro became a pioneering and prolific female journalist in the first half of the 20th century and one of that era's better known authors".
