O'Connor regrets that he knows of no documents or other data that will throw light on the life and labor of his brother, Bishop Michael O'Connor, S.J. . His brother destroyed nearly all of his correspondence, before and after his entrance into the Society of Jesus. A few letters of a personal nature were forwarded from Woodstock after his death. The files of the "Pittsburg Catholic", "The Catholic Church in the Diocese of Pittsburg and Alleghany" by Father Andrew A. Lambing, and the Woodstock Letters are the only sources O'Connor can give. Lambing is correct, in the main, as far as his book refers to the bishop. O'Connor gives a summary of the life of Bishop O'Connor, from his birth until he was called by Father Peter Richard Kenrick to Philadelphia for Bishop Francis Patrick Kenrick O'Connor knows nothing of his Predecessor, Bishop James M.M. O'Gorman . He found no records of O'Gorman's administration when he came to the vicariate and has only met O'Gorman once for a couple of hours. The monks at New Melleray, Iowa would no doubt be able to give a full account of O'Gorman's life and labors. O'Gorman had been Abbot of New Melleray. :: I-2-n A.L.S. 4pp. 8vo.
