Mivart’s first name was St. George. He is not canonized. In fact he died unable to receive the Holy Sacraments.
Actually, I was surprised to see Mivart’s name on the boards today, as this morning his name was mentioned in my Newman reading of the day, and I thought with sadness how he died.
I read a brief summary of his life in Judith F. Champ’s book, “William Bernard Ullathorne, 1806-1889: A Different Kind of Monk”, pp. 481-483. The first two pages are available at this link via Google Books:

and then page 483 continues:
of pseudophilosophic theories’. Samuel Lilly’s book,
Ancient Religion and Modern Thought was equally dangerous, treating alike Buddhism, Hinduism, Zoroastrianism and Confucianism. Ullathorne vehemently insisted that joint episcopal action was needed and even intervention from the Pope himself. Mivart’s work, and reviews in
The Weekly Register,
The Tablet, and
The Dublin Review, in his opinion reflected the dangerous effects of liberal Catholic writing on the Church and the lack of a challenge from authority. Eventually, after Ullathorne’s death, Mivart clashed openly with the Church hierarchy, finding his work on the Index of forbidden books. Bracketed with the Modernists whose path he had paved, he died excommunicated from the Church in 1900.
The 1911 Catholic Encyclopedia has further information on what happened after his death:
