Illinois Pernin came to America at the invitation of
Chicago bishop
James Duggan, who was concerned to reconcile French-speaking Catholics in Chicago, alienated by his predecessor
Anthony O'Regan, and to counteract the influence of anti-Catholic evangelist
Charles Chiniquy, who was leading
French-Canadian-American Catholics into the
Presbyterian Church. From October 1864 to March 1868 Pernin was pastor at St. John the Baptist,
L'Erable,
Iroquois County, Illinois, 15 miles from Chiniquy's church in
St. Anne.
Wisconsin Pernin left Illinois for the new
diocese of
Green Bay, Wisconsin, established in 1868, in the period of Duggan's mental decline that led to his removal from office in April 1869. In ten years in the diocese of Green Bay Pernin was pastor of St. Joseph's,
Robinsonville, December 1868 to September 1869;
St. Peter's,
Oconto, August 1869 to December 1869; Assumption of the Blessed Virgin Mary,
Peshtigo and St. Patrick's,
Marinette (renamed Our Lady of Lourdes by Pernin in June 1873), December 1869 to September 1875; and Sts. Peter and Paul,
Grand Rapids (now Wisconsin Rapids in the
diocese of La Crosse, Wisconsin), September 1875 to October 1878.
Minnesota Pernin spent his last 31 years in Minnesota in the dioceses of
St. Paul and
Winona (now Winona-Rochester): Church of the Crucifixion,
La Crescent, 1878 to 1886; St. Patrick's,
Brownsville, 1886 to 1894; St. Bridget's,
Simpson 1894 to 1897; and St. Joseph's,
Rushford 1897 to 1898. After the diocese of Winona was established in 1889, broken off from that of St. Paul, its first bishop
Joseph Cotter named Pernin its first
vicar general, the diocese's highest office after the bishop. In 1898, upon Pernin's retirement from regular parish ministry and as vicar general, Cotter named him the first regularly appointed resident chaplain of
St. Mary's Hospital,
Rochester, from which developed the institution now known as
Mayo Clinic. Pernin died at St. Mary's on October 9, 1909, aged 87, after 45 years in America. He was buried at St. John's Cemetery (now Calvary Cemetery), Rochester. ==The Great Peshtigo Fire and
