John F. Marion was born in Jersey City, N. J., on the 7th of June, 1867. He attended St. Peter's Parochial School and then entered St. Peter's College, Jersey City. Afterward he read law with Hon. J. Herbert Potts and Frederick Frambach, Jr., in his native city, and was admitted to the bar in November, 1891. Since then he has been actively and successfully engaged in the general practice of his profession in Jersey City. He was a partner of Thomas H. Kelly, Collector of the Port of Jersey City under Cleveland's first administration, until Mr. Kelly's death in 1895, the firm name being Kelly & Marion. He practiced one year alone, and then formed a partnership with Daniel P. Byrnes, under the firm name of Marion & Byrnes, which continued until January 1, 1899. Since then Mr. Marion has practiced alone. He has built up a large and successful legal business and is regarded as one of the able members of the Hudson County bar. He probably has charge of more law work for Catholic institutions than any other lawyer in Eastern New Jersey. He is counsel for St. Peter's College and St. Peter's Church of Jersey City, for the Sisters of Peace of New Jersey, and for St. Joseph's Church of Guttenberg, and one of the counsel for St. Francis Hospital, Jersey City.

Mr. Marion has not only achieved success at the bar, but has also gained distinction for those qualities of citizenship which characterize an energetic, patriotic, and progressive man. In 1895 he received in a postgraduate course the degree of Ph.B. at St. Francis Xavier College, New York City, and for a time wrote many special articles for the New York Catholic News. He is a prominent member of the Knights of Columbus, and one of the charter members of the council in Jersey City, of which he was elected first financial secretary. He is also a member of the Catholic Club of Jersey City, of the Third Ward Democratic Club, and of the Catholic Benevolent Legion. In politics he is an active and ardent Democrat.
